Its why we risk the hatred of the world to share the gospel with so many unwilling to hear it. I'm betting you've read Dante. I wish on no one eternal retribution. I've suffered 2nd degree burns over relatively small parts of my body and don't wish 3rd degree, and worse, continuously on others. I've suffered broken bones and dislocated joints and don't wish that on others. Many choose it. Choose to remain in rebellion against God. I choose to try to talk them out of it knowing many will refuse the knowledge.
It's a place designed to punish Satan and the rest of the rebellious former angels. Remember, in the Old Testament, a single angel of God wiped out 185,000 Assyrians in one night. It's a place that will punish beings of that strength. Into that environment, every unrighteous human will be allowed to remain separate from God for eternity.
