“Though we live in space-age times, we still have stone-age minds. We are competitive and territorial and violent, just like our simian ancestors. There are people who insist this isn’t so, who insist that they could never kill anyone, but they invariably add a telling caveat: “Unless, of course, a person tried to harm someone I love.” So the resource of violence is in everyone; all that changes is our view of the justification.”
