This is my problem with a lot of literature and movies. The Nazis are always unfathomably evil, when in reality, most of them were just people doing their jobs.

I read Eichmann in Jerusalem recently, and the reality is that what Eichmann did was incredibly mundane for the most part. There is someone in ICE right now doing exactly what Eichmann was doing: Coordinating roundups of people made "illegal" by law, and then transporting them to foreign camps and foreign countries. The final solution came very far into the whole sequence of events, and Eichmann presents that he didn't like it at all, but really had no choice in the matter if he didn't want to be made a pariah or face severe personal repercussions. I would be willing to bet there are any number of people inside the US federal government who are thinking exactly that line of thought.
