Every last one of us can kill. Second by second our minds overrule our instincts and our emotions because we're smart and we can think and we're very social animals that care about shame and what others think of us and what we've been told and the consequences of our actions, but every last one of us has a stone cold killer threaded inseparably.

I am an enormous believer in good manners [1].
