I dunno, social manipulation is a pretty powerful tool. The difference between a peaceful loving society and an aggressive and warlike society is in large part controlled by social pressures and perceptions.
The intents of Nazis, Imperial Japanese, Crusaders, etc., can only be explained by their social pressures. Same people born in different place and time would have different intents.
Control what people see and hear and you control what they think.
Einstein quote:
>Few people are capable of expressing with equanimity opinions which differ from the prejudices of their social environment. Most people are even incapable of forming such opinions
