More of a proclamation idea there.
Jesus tells people if they do not believe in Him they will die in their sins.
So unbelievers die with their sins unforgiven them. That death Jesus was referring to was their physical death of their bodies. So they go on to hell with unforgiven sins. And then also they go to the second death at the end. So never any life is possible for those who die in their sins, only a continuing death.
The 'spirits in prison' are all disobedient spirits from that time, including the fallen angels and the Nephilim. Fallen angels and Nephilim get no second chance at salvation, neither do human spirits imprisoned in hell.
3:19 proclaimed to the spirits in prison. Four main interpretations of vv. 19, 20 may be mentioned: (a) Christ as preincarnate and preaching through Noah (2 Pet. 2:5) to the people before the Flood (Gen. 6–8). Noah called them to repentance, but they disobeyed and are now imprisoned. The point of Peter’s argument would then be that as God vindicated Noah then, He would vindicate Christians now. (b) Christ’s preaching in the short interval between His death and Resurrection, during a “descent into hell.” It is said that Christ announced His victory to the spirits of Noah’s wicked contemporaries confined in the realm of the dead. (c) A similar idea is that Christ proclaimed His victory to fallen angels, often identified with the “sons of God” of Gen. 6:2, 4 (cf. Job 1:6; 2:1), in their place of confinement. (d) Christ proclaiming His victory to fallen angels after the Resurrection, at the time of His Ascension into heaven. The point of the last three interpretations is that just as Jesus was vindicated, so too Christians will be vindicated.

"You will note:
1. The preaching of Christ was to the dead of Noah's day.
2. The dead of that day were "disobedient" and perished in the great flood (8 souls were saved)
3. Those who perished (all minus 8) were confined to "prison" aka "spirits in prison".
4. Jesus Christ "preached" to these "disobedient", aka "even the dead", the good news of His triumph.
5. This proclamation occurred after suffering for sin and "being quickened by the Spirit."
6. Net result= judgement "according" to "men in flesh">>>>leading to living "according to God in spirit."
Beyond that I cannot, and will not go. Rose does not believe in chance, first or second or third etc.
I do, however, believe God loses nothing. He is the Source, the Guide, and the Goal of the ta panta. I also believe none of us grasp (including me) the majesty
of our triumphant Lord, aka "the Saviour of all mankind." "
The Scripture under consideration=
"For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:
By which also he went and preached unto the spirits in prison;
Which sometime were disobedient, when once the long suffering of God waited in the days of Noah, while the ark was being prepared, wherein few, that is, eight souls were saved by water.
For unto this end was the gospel preached even to the dead, that they might be judged indeed according to men in the flesh, but live according to God in the spirit."
