“…willing perpetrators.”

“What we do know is that Germans were not forced to be killers.  Those who refused to participate were given other assignments or transferred.  To this day no one has ever found a single example of a German who was executed for refusing to take part in the killing of Jews or other civilians.  Defense attorneys of Germans accused of war crimes during WWII have looked hard for such a case because it would support the claim that their clients were forced to kill.  The Nazi system, however, did not work that way.  There were enough willing perpetrators.  For the most part coercive violence could be reserved for those deemed enemies.” – Doris Bergen, War and Genocide: A Concise History of the Holocaust, pg. 155
