The world has far too much morality, at least in the sense of activity of people's moral instincts. If you look, and this become clear to me as I tried to identify the causes of violence at various scales throughout human history, from police blotters where the biggest motive for homicide is not just amoral predacious: a smuggler killing someone to steal his Rolex, the biggest categories of motives for homicide are moralistic in the eyes of the perpetrator, of the murderer, is capital punishment: killing someone who deserve to die because: whether is a spouse who's unfaithful or someone who distim him in an argument over a parking space or cheated him in a deal. That's why people kill each other: for moral reasons. That is true as large scales as well.If you'll look up at the largest episodes of bloodletting in human history most of them would have moralistic motives: the nazi Holocaust, Pol Pot, Stalin, the Gulag, Mao, the European war of religions, the Crusades, all of them were killing people for, not because they wanted to accumulate vast amounts of money, or huge harems of women, but because they thought they were acting out of a moral cause.
