You'd be wrong. I've got a great-uncle that was a card carrying member of the dutch nazi party. Seems like a pretty clear-cut case. Turns out that he didn't like nazis much, but as a publisher he was required to either be a member of the party or quit his job and starve.

People did what they had to do to survive. It's easy to tell them they were wrong in hindsight.

Just to add so this comment can't be misconstrued later: The nazi party was evil. Committing genocide is bad.
