Ordinary Men (The Forgotten Holocaust). If you like history I highly recommend this. It's a documentary about how thousands of ordinary men like bakers etc. took part in Nazi police / death squads during the Holocaust.
This was unlike the military. They could refuse to take part in the mass murders with no repercussions.
They were responsible for murdering over 2 million civilians (men, women and children) mostly by shooting them.
This was before the concentration / death camps were used for mass genocide. It's not for the faint of heart. History is my favorite and I was unaware of this. When it came out last month it was one of the most watched.
