Yeah, and that's credited as why the Nazi's were so able to compel the citizens of occupied regions to their death. The people in charge tell you to do something? You do it.
I think it was this absolutely horrifying episode of The War Against Humanity that made this point:
The Rape of Humanity at Babi Yar - War Against Humanity 019 - September 1941 Pt. 2
I don't recommend watching it unless you're feeling particularly resilient.
