When we're good, we're very, very good, and when we're bad, we're horrid. This is not news, because we're so much more inventive and we have two hands, the left and the right. That is how we think. It's all over our literature, and it's all over the way we arrange archetypes, the good version, the bad version, the god, the devil, the Abel, the Cain, you name it. We arrange things in pairs like that because we know about ourselves.
