Isn't It True That Some People Are Bad?

David Frum: There's no such thing as a good person or a bad person. We're all somewhere in between, but if you start thinking of yourself as a bad person, then you may start expecting yourself to do bad things. Once you start blaming someone and thinking of them as a jerk, you'll treat them in a very negative way,. And then they'll retaliate and get defensive and mean-spirited.
