"WHY would anyone hurt you? Why would you hurt or kill someone else? Contrary to popular perception, people are rarely violent simply because they lose control and fail to think about right and wrong. They rarely commit violence because they lack empathy and fail to see their victims as fully human. And almost no one is violent because they draw sadistic pleasure from the suffering of others.
"Across cultures and history, there is generally one motive for hurting or killing: people are violent because it feels like the right thing to do. They feel morally obliged to do it.
"Loss of control, lack of empathy, dehumanisation, self-interest: these are factors that help facilitate violence, but none of them account for the motives underlying most acts of violence. When people impulsively lash out, on the whole they don't simply lash out randomly."
