Hell is justified.

It's actually pretty hard to motivate yourself to torture.  The people who do it professionally get rotated so that it doesn't scramble their shit.  I think that you might find it alot easier than you think, even with hitler, to pass on torture.

Humans are not hard wired to torture others for the most part. But for the vile dictators who have come about in human history, there is always something missing in their upbringing even if  a mere lack of empathy. 

And "rotating" people out, still does not change the holocaust, Hitler, Stalin or Po Pot.  Attila The Hun,  was a brutal authoritarian. And even in ancient China, the Terracotta Warriors were living under a extreme authoritarian rule that would make Orwell blush. 

As long as our species has existed in our current form, there have been points worldwide where a leader has managed to get otherwise reasonable people to do horrible things.

Lack of empathy isn't necessarily about a person's upbringing.  Some people just aren't wired for empathy.  Some of those may learn to fake it to fit in better, if they care to do so.  Empathy is being able to understand and relate to what others are experiencing usually through having a similar experience.

Teaching a child to share and not to hit other children is part of upbringing.  Learning what not to do doesn't ensure there is any empathy is involved but merely knowing there are rules that are to be followed. 

Manners and acceptable behavior can be taught.  Empathy - in the real sense - can't.

The most common characteristic of a serial murderer is a lack of empathy.

Stir that up with some animal torture and a heavily religious domineering mother and throw in some late age bed-wetting and you have most of the making for serial killing.
