Hell is justified.

[Mister Agenda]

That's why I suggested a fixed amount of time.

Nobody should justify what Hitler did. But lets say you gave 1,000 years for each of the 6 million Jews, and 50 million worldwide, no that would not be eternity, but after that finite time, nobody can claim someone like Hitler could or would learn their lesson. Even if one were not to torture Hitler in an "eternity" and gave him a fixed time, that still would not work because someone like that is irredeemable. 

All I was pointing out was that if there were a "hell" which there is not, Hitler would be one case one would be hard pressed not throw him in.

I think you underestimate the transformative power of profound torture. One of the things that is unjust about an eternity of it is that it doesn't take that long for the subject of torture to truly believe what the torturer wants them to believe if that will get the torture to stop. I'd be a believer in seconds flat if I was burning, and it wouldn't take much longer (definitely not a thousand years) to get me to start torturing other people if that's what it took to make my own torture stop. It could literally change me into a different person. Hell, magic mushrooms could literally change me into a different person. Experience in general changes us. It's easy to be cruel when you're in charge and no one will stand up to you, it would be a bit harder if you were deposed and given a big dose of what you've been dishing out.

IMHO, you may have more insight into Hitler's intransigence than I do. But if he can stand thousands of years of horrific torture without learning not to do the things he's being tortured for, I think that counts as a superhuman attribute, truly invincible ignorance.
