Milgram was interested in understanding how Nazi SS Officers and soldiers could commit the atrocities they did in the Holocaust. Milgram reasoned that there wasn’t a group of people who shared a common goal through free will, but a group of people who obeyed a common goal through successive obedience: Hitler sends his orders, his subordinates obey, their subordinates obey and so on. Milgram theorised that it was the social situation that caused ‘normal’ people to kill millions of innocent people.
