well..Evil-doers will have all the eternity to meditate upon what they did and who they were. And what they became.
The thought of having hurt so many people is like a hammer that hits your cranium restlessly. If that's not Hell...what is it?
There's plenty of people who don't care about others, either through poor experience or some kind of sociopathic condition. Such people would actually find Heaven eternal torture.
Hm... that would be an interesting way of looking at the Christian hell/heaven dichotomy. Both go to the same place, the realm of God; for good people, that's a place of wonder and happiness, but bad people find nothing but suffering and torture there. Internet personalities that portray cynicism oftentimes will communicate a strong dislike of happiness in other people, which is certainly a joke in that case, but is likely something real people actually feel in some cases. It would be an interesting concept to explore in some kind of parody.
Granted, this could come from my Asatruar beliefs: the Goddess Hel has two forms: that of the most beautiful woman conceivable, and that of the most hideous form that could be conceived. A dying person will get the beautiful form if death is not feared, but will get the hideous form if death is feared.
