As an aside, i recommend the book "Ordinary Men". It tells the story of middle aged reserve policemen that weren't indoctrinated Nazis ( and a non insignificant part of them were communist-sympathising dock workers pre-war) and their trail of atrocities in Poland. It makes a decent case that there's more to it than "was just a Nazi", even if really isn't "just followed authority blindly".
