I know I'm going to take heat for this, but here goes:
People like to say "he needs therapy" all the time about people like Michael Jackson. And while therapy is a great help to some people, it seems a waste of time for pedophiles. Why bother treating them, when they're not sick, they're just plain EVIL? He's a grown man who knew full well what he was doing, that it was wrong, and that it would hurt these kids now, and for the rest of their lives- because you never ever get over being molested.
When I've got cockroaches in my house, I don't worry myself trying to rehabilitate them, retrain them, or discover the motivations for their behavior- I get some spray and I f%*king obliterate the nasty beasts before they make my family sick. It works on roaches, it would work even better on child molesters.
