Isn't it entirely possible that the world as it is isn't how God would prefer it? God didn't want us to have knowledge of good vs evil. Furthermore, the final chapter of Revelation implies that salvation would be a share in the tree of life and the Holy City and the punishment for the wicked will be the plagues rather Heaven and Hell.
18 I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll. 19 And if anyone takes words away from this scroll of prophecy, God will take away from that person any share in the tree of life and in the Holy City, which are described in this scroll. Revelation 22:18
If God were to punish with the plagues, one would have to recognize the parallels to the Old Testament and assume that the ones that will be punished will be the people that don't recognize God's Commandments. Instead they worship men, buildings, and books. Or practice adultery, murder, theft. They value items possessions etc. They take judgment from God and murder in his name. But their actions in doing so show a lack of faith in God. Those would have to be the crimes that God sees as the worst seeing as how they were condemned by the laws He gave to the children of Abraham.
The distresses were for a purpose - to motivate a change in those willing to change.
Roam the streets of Jerusalem.
Look around and take note.
Search her public squares to see
Whether you can find a man who acts with justice,
One who seeks to be faithful,
And I will forgive her.
Even if they say: "As surely as Jehovah is alive!"
They would still swear to what is false.
O Jehovah, do your eyes not look for faithfulness?
You struck them, but it made no impact on them. (Lit., "they did not become weak.")
You exterminated them, but they refused to accept discipline.
They made their faces harder than a rock,
And they refused to turn around.
- Jeremiah 5:1-3
There is no purpose to eternal torment but to sate the desire of a sadist. Instead the Bible says "God is love." (1 John 4:8)
Rather than putting the wicked into eternal misery, they are simply put out of the righteous ones' misery.
Let the irredeemable sleep forever, where they can be eventually forgotten.
For look! I am creating new heavens and a new earth;
And the former things will not be called to mind, (or "remembered.")
Nor will they come up into the heart.
- Isaiah 65:17
