A certain imminent movie release got us thinking about Nazis, and how, unusually, for an actual historical movement, they've developed into the kind of perfect narrative scapegoat that's normally reserved for entities of entirely fictional origin.
Which is not to say they don't deserve it, because they
do. Overwhelmingly so. It makes perfect sense that they're right up there with zombies, demons, and non-sentient robots as entities that heroes are allowed to be absolutely brutal to without catching flack for it or otherwise in some way exploring the moral consequnces of their actions.
