There are different reasons why people commit crimes. Some do out of need: they don't see a better option. Others do so out of opportunity: it's easy and they can get away with it. And I suppose a rare group does it out of a commitment to pure evil.

I have very different degrees of sympathy for these groups. The first group needs access to better options. The second group needs to be held accountable. The third group cannot really be allowed to participate in our society.
