Before Christ's earthly resurrection, the righteous were not let out of Hades to temporarily visit Jesus on His mount of transfiguration, but instead were residing in the glory of "Paradise:"

Matthew 17:2 And [Jesus] was transfigured before them, and His face shone like the sun, and His garments became white as light.
Matthew 17:3 And hey, there appeared to them Moses and Elijah, talking with Him.

Mark 9:2 And after six days Jesus took with Him Peter and James and John, and led them up a high mountain apart by themselves; and He was transfigured before them,
Mark 9:3 and His garments became glistening, intensely white, as no fuller on earth could bleach them.
Mark 9:4 And there appeared to them Elijah with Moses; and they were talking to Jesus.

And, again, before Christ's earthly resurrection:

Luke 23:43 And [Jesus] said to [the penitent thief on a cross who had called Jesus 'Lord']: "Truly, I say to you, today you will be with me in Paradise."

Second Corinthians 12:3 And I know that this man was raptured into Paradise . . . whether in the body or out of the body I do not know, God knows . . .

The following verses:

Acts 2:29 "Brethren, I may say to you confidently of the patriarch David that he both died and was buried, and his tomb is with us to this day.
30 Being therefore a prophet, and knowing that God had promised with an oath to him that He would set one of his descendants upon his throne,
31 he foresaw and spoke of the resurrection of the Christ, that He was not abandoned to Hades, nor did His flesh see corruption.
32 This Jesus God raised up, and of that we all are witnesses."

"Abandoning to Hades" does not mean that the temporarily-dead Jesus got into Hades, got tortured with fire there for a while purgatorial-style, then eventually managed to get out.

Instead, "abandoning," in this case, meant that He neither got in Hades nor got out, but instead bypassed it, escaped it completely -- though by being planted in some rich guy's grave he metaphorically (and only in that sense) "descended to the lower parts of the earth".

In other words, He did descend into His [ temporary ] grave after "falling asleep" (another metaphor) . . .

Ephesians 4:8 Therefore it is said, "When He ascended on high He led a host of captives, and He gave gifts to humans."
Ephesians 4:9 In saying, "He ascended," what does it mean but that He had also descended into the lower parts of the earth?
Ephesians 4:10 He who descended is He who also ascended far above all the heavens, that He might fill all things. [ see Colossians 1:15-17 about that ]

. . . but NOT momentarily or longer being consigned to and confined within: "Hell" -- despite what major "christian" creeds state to the contrary -- the exact and complete wording of all three is found no where within the totality of the Sacred-66-books Judeo-Christian Old-and-New-Testaments Holy Bible.

What Christ, upon His temporary and not permanent death on a cross, did descend into was: Sheol - which term was used in the Old Testament for the [ temporary ] abode of both righteous and wicked dead humans.

Why is Hades "temporary?"

It is because those consigned to Hades will be resurrected on The Last Day to stand and be cursed as wicked "goats" in the Matthew-chapter-25-mentioned Last Judgment, thereafter transferred from Hades to The [Outer-Darkness] Lake of Fire:

Revelation 20:13 And the sea gave up the dead in it, Death and Hades gave up the dead in them, and all were judged by what they had done.
Revelation 20:14 Then Death and Hades were thrown into The Lake of Fire. This is The Second Death, The Lake of Fire;
Revelation 20:15 and if any one's name was not found written in The Book of Life, they was thrown into The [Outer Darkness] Lake of Fire.

"Outer Darkness?"

Matthew 22:13 Then the king said to the attendants, 'Bind [him] hand and foot, and throw [him] into The Outer Darkness; there humans will weep and gnash their teeth.'

Like being deep down in an underground cave, when all the lights are suddenly turned off. A guy or gal cannot even see his or her hand in front of themselves in the profound and scary blackness.

So, Jesus was in Sheol, but neither Hell nor Hades.

Temporarily.

Psalm 139:7 Where shall I go from your Spirit? Or where shall I run to from your presence?
8 If I ascend to heaven, you are there! If I make my bed in Sheol, you are there!
9 If I take the wings of the morning and reside in the farthest parts of the sea,
10 even there your hand shall lead me, and your right hand shall hold me.
11 If I say, "Let only darkness cover me, and the light about me be night,"
12 even the darkness is not dark to you, the night is bright as the day; for darkness is as light with you.
13 For you did form my inward parts, you did knit me together in my mother's womb.
14 I praise you, for you are fearful and wonderful. Wonderful are your works! You know me right well;
15 my frame was not hidden from you, when I was being made in secret, intricately wrought in "the depths of the earth." [ another metaphor -- like "the everlasting hills" metaphor of Genesis 49:26 and Deuteronomy 33:15 . . . which are not everlasting whatsoever according to Habakkuk 3:6 ]
16 Your eyes saw and considered my non-formed substance; in your book were written, every one of them, the days that were allotted for me, when as yet there were none of them.

The New Testament makes it clear that Sheol is actually comprised of two very-different localities and/or states of existence regarding righteous deceased and concerning wicked deceased.

For the good guys and gals, their [ temporary ] residence, upon their earthly demise, is called: Paradise - a place of bliss in the company of angels and souls of deceased righteous humans.

Against the bad guys and gals, their [ temporary ] residence, upon their earthly demise, is called: Hades - a place of fiery torment in solitary confinement wherein (according to the story or account Jesus is said to have given us in Luke chapter 16) only limited communication has occurred to one select soul in Paradise.

And the following occurred before Christ's resurrection:

Luke 16:22 The poor man died and was carried by the angels to Abraham's bosom. The rich man also died and was buried;
23 and in Hades, being in torment, he lifted up his eyes, and saw Abraham far off and Lazarus in his bosom.
24 And he called out, 'Father Abraham, have mercy upon me, and send Lazarus to dip the end of his finger in water and cool my tongue; for I am in anguish in this flame.'
25 But Abraham said, 'Son, remember that you in your lifetime received your good things, and Lazarus in like manner evil things; but now he is comforted here, and you are in anguish.
26 And besides all this, between us and you a great Chasm has been fixed, in order that those who would pass from here to you may not be able, and none may cross from there to us.'
27 And he said, 'Then I beg you, father, to send him to my father's house,
28 for I have five brothers, so that he may warn them, lest they also come into this place of torment.'
29 But Abraham said, 'They have Moses and the prophets; let them hear them.'
30 And he said, 'No, father Abraham; but if some one goes to them from the dead, they will repent.'
31 He said to him, 'If they do not hear Moses and the prophets, neither will they be convinced if some one should rise from the dead.'"

If more persons took the above narrative seriously (along with the predictions below), and not relegate them to myth nor allegory, there might be far fewer "deliberate" suicides, school-or-wherever genocide incidents ending with self-inflicted fatal gunshot wounds to the head before the police arrive to gun down the murderer or murderess down to forever terminate their insane rampage.

Death does not "end it all" -- despite disbelief of apostates and infidels resulting from them self-deceiving themselves into damnable lying delusion against revealed factual reality accurately and faithfully recorded in Holy Scripture.

Isaiah 26:19 Your dead shall live, their bodies shall rise. Dwellers in the dust, awake and sing for joy! For your dew is a dew of light, and on the land of the shades you will let it fall.

Isaiah 28:14 Therefore hear the word of the LORD, you scoffers, who rule this people in Jerusalem!
15 Because you have said, "We have made a covenant with death, and with Sheol we have an agreement; when the overwhelming scourge passes through it will not come to us; for we have made lies our refuge, and in falsehood we have taken shelter";
16 therefore thus says the Lord GOD, "Hey, I am laying in Zion for a foundation a stone, a tested stone, a precious cornerstone, of a sure foundation: 'He who believes will not be in a hurry.'
17 And I will make justice the line, and righteousness the plummet; and hail will sweep away the refuge of lies, and waters will overwhelm the shelter."
18 Then your covenant with death will be annulled, and your agreement with Sheol will not stand; when the overwhelming scourge passes through you will be beaten down by it.
19 As often as it passes through it will take you; for morning by morning it will pass through, by day and by night; and it will be sheer terror to understand the message.
20 For the bed is too short to stretch oneself on it, and the covering too narrow to wrap oneself in it.
21 For the LORD will rise up as on Mount Perazim, He will be wroth as in the valley of Gibeon; to do His deed -- strange is His deed! and to work His work -- alien is His work!
22 Now therefore do not scoff, lest your bonds be made strong; for I have heard a decree of destruction from the Lord GOD of hosts upon the whole land.

Daniel 12:2 And many of those who sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.

John 5:28 Do not marvel at this; for the hour is coming when all who are in the tombs will hear His voice
John 5:29 and come forth -- those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of damnation.

Acts 24:15 . . . there will be a resurrection of both the just and the injust.

Revelation 20:12 And I saw the dead, great and small, standing before the throne, and books were opened. Also another book was opened, which is The Book of Life. And the dead were judged by what was written in the books, by what [ works? not faith alone? ] they had done.

"Deliberate" suicides? What is meant by "deliberate?"

Realize that all of us humans are more-or-less involuntarily trapped within a hopelessly-polluted environment and thus reluctantly (and rather non-thinkingly) doing things to slowly destroy ourselves (which homicide is selfishly and even maliciously caused by Satan, his demons, and their human accomplices around us).

We breathe polluted air, drink polluted water, and eat polluted food concocted by evil bastards and bitches transporting it all with their poison-emitting vehicles -- which lethal pollution and poison is causing slow death to everyone in various increasingly-obvious-and-severe insidiously-handicapping forms -- consequences of imposed and non-solicited spam-like laziness, greed, sexual immorality, idolatry, and blasphemy emanating and spewed out from the damned-to-be.

For suicide (also known as self-murder) to be considered bonafide "suicide," willful and non-authorized life termination against innocent humans must be involved.

Let's say that you and I were confined in some huge compactor, with the walls of such slowly closing in on us from both sides. Let's also imagine that there was a loaded pistol on the floor.

It would be illegitimate killing (thus suicide) if either one of us took the pistol and blew our brains out before the compactor squeezed us to death. But it would not be illegitimate killing on our part if we simply resigned ourselves to the mortal fate of becoming fatally crushed by the moving walls we could not stop even after trying our best to stop them from closing in on us.

Why it would be suicidal (self-murder) to prematurely blow our brains out with the pistol is because we would not know if the compactor would have stopped just before squishing us to death, and should wait for it to finally do so (if that is God's will)-- thus placing the responsibility on the compactor for killing us (whether considered legitimate as an execution or instead illegitimately as a murder).

To reside in a polluted environment we cannot reasonably escape from, and thus reluctantly get sick and eventually die from cannot be considered [self-murder] suicide. But, lying down behind a stationary vehicle with its engine running and sucking up the exhaust with our mouths on the tailpipe would be considered [self-murder] suicide.

Could the act of Abraham beginning to barbarically knife his own son Isaac to death on some religious altar been considered attempted murder?

Not if Abe considered that the Lord was able and perhaps willing to miraculously bring the stabbed kid back to life:

Genesis 22:10 Then Abraham put forth his hand, and took the knife to slay his son.
11 But the angel of the LORD called to him from heaven, and said, "Abraham, Abraham!" And he said, "Here am I."
12 He said, "Do not lay your hand on the lad or do anything to him; for now I know that you fear God, seeing you have not withheld your son, your only son, from me."
13 And Abraham lifted up his eyes and looked, and hey, behind him was a [ Christ-like lamb-of-God-for-death-on-a-cross-foreshadowing? ] ram, caught in a thicket by his horns; and Abraham went and took the ram, and offered it up as a burnt offering instead of his son.
14 So Abraham called the name of that place The LORD will provide; as it is said to this day, "On the mount of the LORD it shall be provided."
15 And the angel of the LORD called to Abraham a second time from heaven,
16 and said, "By myself I have promised," says the LORD, "because you have done this [ and acted like Canaanite-like barbarians who also slay and sacrifice their offspring for ritualistic pagan purposes? ], and have not withheld your son, your only son,
17 I will indeed bless you, and I will multiply your descendants as the stars of heaven and as the sand which is on the seashore. And your descendants shall possess the gate of their enemies,
18 and by your descendants shall all the nations of the earth bless themselves, because you have obeyed my voice."

Hebrews 11:17 By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was ready to offer up his only son,
Hebrews 11:18 of whom it was said, "Through Isaac shall your descendants be named."
Hebrews 11:19 He considered that God was able to raise men even from the dead; hence, figuratively speaking, he did receive him back.

Could the three friends of Daniel be guilty of conspiracy to commit (and not "perform") suicidal murder against themselves by not bowing to Nebby's idol, the consequence of which caused them thus to be headed for the furnace and not whisked away in pre-Trib Rapture?

Only if they had not suggested that God could deliver them - somehow, and some way:

Daniel 3:10 You, king, have made a decree, that everyone who hears the sound of the horn, pipe, lyre, trigon, harp, bagpipe, and every kind of music, shall fall down and worship the golden image;
11 and whoever does not fall down and worship shall be tossed into a burning fiery furnace.
12 There are certain Jews whom you have appointed over the affairs of the province of Babylon: Shadrach, Meshach, and Abednego. These men, king, pay no heed to you; they do not serve your gods or worship the golden image which you have set up."
13 Then Nebuchadnezzar in furious rage commanded that Shadrach, Meshach, and Abednego be brought. Then they brought these men before the king.
14 Nebuchadnezzar said to them, "Is it true, Shadrach, Meshach, and Abednego, that you do not serve my gods or worship the golden image which I have set up?
15 Now if you are ready when you hear the sound of the horn, pipe, lyre, trigon, harp, bagpipe, and every kind of music, to all down and worship the image which I have made, well and good; but if you do not worship, you shall immediately be cast into a burning fiery furnace; and who is the god that will deliver you out of my hands?"
16 Shadrach, Meshach, and Abednego answered the king, "Nebuchadnezzar, we have no need to answer you in this matter.
17 If it be so, our God whom we serve is able to deliver us from the burning fiery furnace; and He will deliver us out of your hand, king.
18 But if not, be it known to you, king, that we will not serve your gods or worship the golden image which you have set up."

Could Jesus, who had resurrect-dead-guys power, giving Himself up to lynching and pseudo-"execution" murder because of jealous and disbelieving jews plus compliant understandably-antisemitic Romans, thus be accused of, by default, being suicidal and not escaping logical-consequence fatality?

Christ would have been so guilty, IF the following had not first been predicted and had come to pass:

Mark 9:31 . . . He was teaching His disciples, saying to them, "The Son of Man will be delivered into the hands of humans, and they will kill Him; and when He is killed, after three days He will rise."
Mark 10:34 and they will mock Him, and spit upon Him, and scourge Him, and kill Him; and after three days He will rise."

Luke 24:7 . . . the Son of man must be delivered into the hands of sinful humans, and be crucified, and on the third day rise."

Matthew 27:50 And Jesus shouted out with a loud voice and yielded up His spirit.
51 And hey, the curtain of the temple was torn in two, from top to bottom; and the earth shook, and the rocks were split;
52 the tombs also were opened, and many bodies of the saints who had fallen asleep were raised,
53 and coming out of the tombs after His resurrection they went into the holy city and appeared to many.
54 When the centurion and those who were with Him, keeping watch over Jesus, saw the earthquake and what took place, they were filled with awe, and said, "Truly this was the Son of God!"

No wonder He had said of them for their behalf:

Luke 23:34 And Jesus said, "Father, forgive them; for they know not what they do..."

Matthew 27:64 Therefore order the sepulchre to be made secure until the third day, lest his disciples go and steal him away, and tell the people, 'He has risen from the dead,' and the last fraud will be worse than the first."

Matthew 28:7 Then go quickly and tell His disciples that He has (not is!) risen from the dead, and hey, He is going before you to Galilee; there you will see Him. Wow, I have told you."
8 So they left quickly from the tomb with fear and great joy, and ran to tell His disciples.
9 And hey, Jesus met them and said, "Hail!" And they came up and took hold of His feet and worshiped Him.
10 Then Jesus said to them, "Do not be afraid; go and tell my brethren to go to Galilee, and there they will see me."
11 While they were going, hey, some of the guard went into the city and told the chief priests all that had taken place.
12 And when they had assembled with the elders and taken counsel, they gave a sum of money to the soldiers
13 and said, "Tell people, 'His disciples came by night and stole Him away while we were asleep.'
14 And if this comes to the governor's ears, we will satisfy him and keep you out of trouble." [ And so we will enrage Pilate and his endangered-by-presumed-desertion-at-the-Tomb Roman guards even more than we already have by putting him and his under duress to adjudicate unjustly against Jesus and now lie on top of it so that they eventually gang up on us in vicious and livid resentment and retaliation by thankfully destroying us in Jerusalem during the future-holocaust siege in 70 A.D. ]
15 So they took the money and did as they were directed; and this [ fabricated and dishonest ] story has been spread among the jews to this day.

Luke 24:13 And hey, two of them went that same day to a village called Emmaus, it being about sixty stadia from Jerusalem.
14 And they talked to each other of all these things which had happened.
15 And while they talked and reasoned, it happened that Jesus Himself drew near and went with them.
16 But their eyes were held so that they could not know Him.
17 And He said to them, "What words are these that you have with one another as you walk, and are so sad?"
18 And one of them, whose name was Cleopas [ who cares what his name was? ], answered and said to Him, Are you only a stranger in Jerusalem and have not known the things which have occurred there in these days?
19 And He said to them, "What things?" And they said to Him, "The things concerning Jesus of Nazareth, who was a man, prophet mighty in deed and word before God and all the people,
20 and how the chief priests and our rulers delivered Him to the judgement of death, and have crucified Him.
21 But we had trusted that He was the One who was about to redeem Israel. And besides all this, today is the third day since these things were done.
22 Yes, and also some of our women astounded us, having been early at the tomb;
23 and when they did not find His body, they came saying that they had also seen a vision of angels, who said that He was alive.
24 And some of those with us went to the tomb and found it even as the women had said. But they did not see Him."
25 And He said to them, "Fools [ and anyone who calls someone a 'fool' is bound for hellfire? ] and slow of heart to believe all things that the prophets spoke!
26 Was it not necessary for the Christ to suffer these things and to enter into His glory?"
27 And beginning at Moses and all the prophets, He expounded to them in all the Scriptures the things regarding (and not "concerning") Himself.
28 And they drew near the village where they were going. And He appeared to be going further.
29 But they constrained Him, saying, "Stay with us, for it is toward evening and the day is far spent. And He went in to stay with them."
30 And it happened as He reclined with them, taking the loaf, He blessed it, and breaking it, He gave to them.
31 And their eyes were opened, and they knew Him. And He became invisible to them.
32 And they said to one another, "Did not our heart burn within us while He talked with us by the way and while He opened the Scriptures to us?"
33 And they rose up the same hour and returned to Jerusalem and found assembled the Eleven and those with them.
34 And they said, "The Lord has (not is) indeed risen, and has appeared to Simon."
35 And they told what things had happened in the way, and how He had been known by them in breaking of the loaf.
36 And as they spoke this, Jesus Himself stood in their midst, and said to them, "Peace to you!"
37 But they were terrified and filled with fear, for they thought they saw a spirit.
38 And He said to them, "Why are you troubled, and why do thoughts arise in your hearts?
39 See and consider My hands and My feet, that I am He! Handle Me and see, for a spirit does not have flesh and bones as you see that I have."
40 And when He had spoken this, He showed them His hands and feet.
41 And while they still did not believe for joy, and wondered, He said to them, "Have you any food here?"
42 And they handed to Him a piece of a broiled fish and of a honeycomb.
43 And He took it and ate before them.
44 And He said to them, "These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the law of Moses and in the Prophets and in the Psalms about me."
45 And He opened their mind to understand the Scriptures.
46 And He said to them, "So it is written, and so it was necessary for Christ to suffer and to rise from the dead the third day,
47 and that repentance and remission of sins should be proclaimed in His name among all nations, beginning at Jerusalem.
48 And you are witnesses of these things.
49 And hey, I send the promise of My Father on you. But stay in the city of Jerusalem until you are clothed with power from on high."
50 And He led them out as far as Bethany. And lifting up His hands, He blessed them.
51 And it happened as He blessed them, He withdrew from them and was carried up into Heaven [ NASA-rocket style? ].
52 And worshiping Him, they returned to Jerusalem with great joy.
53 And they were continually in the temple, praising and blessing God. Amen.

John 20:9 . . . for as yet they did not know the scripture, that He must rise from the dead.

Acts 17:3 . . . explaining and proving that it was necessary for the Christ to suffer and to rise from the dead, and saying, "This Jesus, whom I proclaim to you, is the Christ."
Acts 26:23 . . . that the Christ must suffer, and that, by being the first to rise from the dead, He would proclaim light both to Jews and others."

All throughout the Bible, good-guy prophets seemed to (at least temporarily) have a [ suicidal ] Death Wish:

Genesis 46:30 Israel said to Joseph, "Now let me die, since I have seen your face and know that you are still alive."
Judges 16:30 And Samson said, "Let me die with the Philistines." Then he bowed with all his might; and the house fell upon the lords and upon all the people that were in it. So the dead whom he slew at his death were more than those whom he had slain during his life.
First Kings 19:4 But [Elijah] himself went a day's journey into the wilderness, and came and sat down under a broom tree; and he asked that he might die, saying, "It is enough; now, LORD, take away my life; for I am no better than my fathers."
Job 3:3 "Let the day perish wherein I was born, and the night which said, 'A man-child is conceived.'"
Jeremiah 20:14 "Cursed be the day on which I was born! The day when my mother bore me, let it not be blessed!"
Jonah 4:3 "Therefore now, LORD, take my life from me, I beg you, for it is better for me to die than to live."

Philippians 1:21 "For to me, to live, is Christ, and to die is gain.
Philippians 1:22 If it is to be life in the flesh, that means fruitful labor for me. Yet which I shall choose I cannot tell.
Philippians 1:23 I am hard pressed between the two. My desire is to leave and be with Christ, for that is far better."

Yet, none of them died in the spot, or even real soon thereafter. No euthanasia allowed, nor assisted suicide permitted -- even though they eventually got their wish (but only at the time and in the way God had arranged for them to so do):

Deuteronomy 30:19 I call heaven and earth to witness against you this day, that I have set before you life and death, blessing and curse; therefore choose life (not abortion homicide), that you and your descendants [ not mere surgically-removable fetal tissue not your own nor even part of your own body, but a separate human soul you have been Divinely appointed to be a responsible caretaker of ] may live
Psalm 118:17 I shall not die, but I shall live, and recount the deeds of the LORD.
Isaiah 51:14 He who is bowed down shall speedily be released; he shall not die and go down to the Pit, neither shall his bread fail.
Habakkuk 1:12 Are you not from everlasting, LORD my God, my Holy One? We shall not die. LORD, you have ordained them as a judgment; and you, Rock, have established them for chastisement.
Philippians 1:25 Convinced of this, I know that I shall remain and continue with you all, for your progress and joy in the faith.

None of the above "played God" by arrogantly or defiantly "taking matters into their own hands" pertaining to their deaths, and anyone else's.
