Yes, but I think that the problem is bigger than these people, and that they are only the manifestation of the problem. They may never get what they deserve and don't learn the lesson, but society, on the contrary, does learn what it must learn and act accordingly. In this way, people like that don't have that power again. And as far as I know, that is the most we can do and what we need to do. We cannot change the world and how things are, but we can change ourselves and how we are.
