“Along with ideological indoctrination, a vital factor touched upon but not fully explored in Milgram’s experiments was conformity to the group. The battalion had orders to kill Jews, but each individual did not. Yet 80 to 90 percent of the men proceeded to kill, though almost all of them—at least initially—were horrified and disgusted by what they were doing. To break ranks and step out, to adopt overtly nonconformist behavior, was simply beyond most of the men. It was easier for them to shoot.”
