Why don't you give us an answer to this question since so far you have done a great job harmonizing scripture with the natural world?
Because i already have the same answer i've had since i first learned the Bible in the Orthodox Church.
We leave judgment up to God and that's it.
Okay, I will begin by noting that anyone who thinks instead of going to so much trouble to provide Messiah's sacrificial atonement that God should punish each individual for his/her own sins thinks too highly of himself and too little of the holiness of God. Even though some sins, such as murder, seem worse than others quantitatively, because they cause more obvious harm, all sin—even that of omission (JM 4:17)—is evil qualitatively and equivalent to murder for being diametrically opposed to the perfect will of God (JM 2:10-11).
Thus, while it might seem that the just consequence for your own sins (or for the poor adolescent in outer Mongolia who did not seek God mentioned previously) would be a hell much less horrible than for someone like Hitler, all ungodly souls are on Satan’s side and cannot earn heaven by trying to be good without cooperating with God. So instead of seeking salvation our own way, it is wise to be grateful for grace and ask for clarification of one’s (mis)understandings in heaven.
Because perfect justice is not attained during this earthly existence, there is a resurrection and judgment (HB 9:27-28), when those who serve the Spirit of love (although imperfectly, PHP 3:12) are separated from demonic souls who do not even want to try to cooperate with the Holy Spirit (MT 25:31-46). Otherwise, there would be no ultimate justice and the entire biblical revelation would make no sense (1CR 15:14&19). If atheists/evil-doers remained unconscious after death, such ignorance would be relative bliss and morality would be nullified (ECC 2:12-17).
Thus, hell (as a potential destiny) as well as heaven is good/part of the duo of desirables (DOD)!
The horror of self-condemnation for serving Satan is this: apparently the misery of hell does not motivate genuine repentance. Thus, God abandons people assigned to hell or second death (RV 20:6, RM 1:28-32), because they are hopelessly corrupt (JN 6:44).
This destiny is eternal for anyone whose sins are infinite. For the rest, hell will end in destruction or non-existence after justice is achieved per the following passages:
JN 17:12, “None has been lost except the one doomed to destruction so that Scripture would be fulfilled.”
RM 9:22, “What if God, although choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction?”
GL 6:8a, “Whoever sows to please their flesh, from the flesh will reap destruction.”
PHP 3:19a, “Their destiny is destruction.”
2THS 1:9a, “They will be punished with everlasting destruction.”
2PT 3:7, “By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of the ungodly.”
Because unrepentant/unseeking souls are annihilated after being appropriately punished in hell, God is both just regarding the ungodly and loving toward those who repent, receive His Holy Spirit and thus reflect Christ's love in the natural world imperfectly and then sufficiently perfectly in the supernatural heaven eternally.
