" The way people behave depends on the basic moral tests and norms in a society. Naturally, the Khmer Rouge, Al-Qaeda terrorists, respectable middle-class Europeans, and, say, members of the Komosol in the 1930's, would behave quite differently in identical situations. But that wouldn't change the essential point. The ration of altruists and egoists, even among Benedictine monks and members of the Gestapo, is the same. It's just that their altruism and egotism are expressed differently. "
