I see it this way:
Hitler had a crappy life leading up to his power, and after attaining such absolute power, he was corrupted absolutely. Thus, acted on his own desires, and as he was so powerful, no one would argue with him or else they'd be the next in line for execution.
No, Nazis were not bad people, most of them just were part of it because it really gave them a natural high. They felt like they existed for something, they felt closer to one another. But the feeling led to arrogance which then led to violent actions.
I know of someone who lived after the Nazis reign of power, and he felt really sad that it all fell apart. Not because he felt great about what he did, it was because he missed the fact tht everyone wanted to work, eat, and live really as a single unit. They felt strong because they all were really in sync with one another.
I also know of another who lived on the East side of the Berlin wall. She had this same feeling, because living in a socialist community you didn't have anything else other than each other. She said, she didn't care that it took forever to get things you wanted, like a car for instance. It was the fact that they all had a common enemy that made them all most a little closer together. That was what she missed, being together, being one, having people to be able to turn to.
As a closing note: Hitler himself i feel was not a bad person, he just knew how to panipulate people, and he was very charismatic. He just misused his power. Though if you think about it, how else was he going to band them together?
"My people, the SNAILS (insert ANYTHING here other than Jews) in this country have been our downfall!?"
Personally, had he directed the country to better channel their power to achieve something better through constructive, rather than destructive methods, i probably wouldn't have minded being a part of it.
Because i must say, in our present times, i feel really without anything, our society is lacking substance now a days.
