“ But do you imagine there’s a certain type of person in the world who conforms to the idea of a ‘bad person'? You’ll never find someone who fits that mold neatly, you know. On the whole, all people are good, or at least they’re normal. The frightening thing is that they can suddenly turn bad when it comes to the crunch. That’s why you have to be careful. ”
