One thing many people forget is that Nazis, although totally evil, were also a very weird, eccentric, and strange group of people. Some, like Hitler, had been petty criminals in their younger days, some (like Himmler) believed in the Norse Gods and thought that Thor and his hammer Mjolnir actually existed, among other supernatural artifacts, and sent teams of Nazis around the globe to retrieve them for Nazi use, some (like propaganda minister Goebbels) believed in astrology, and so on. In many cases they were freaks and fringe nutcases (as well as virulent racists and lots of other terrible things) in their youths who managed to become the absolute rulers of a powerful nation, created one of the most powerful personality cults of all time, and committed acts of horror on tens of millions in many different nations. Miller, I think, would fit right in with that group a century or so ago.
