my hypothesis is that violence, psychopathy, individualism only emerge as society grows and becomes more complex, it becomes more beneficial for the individual than collaboration. for example in a band of 100 people you would get kicked out or killed if you hurt the band or act egoistically but in a society you arise to the top when you act egoistically and are machiavellian. look at how chieftains and royal families became what they are, look at billionaires, etc
