Are you talking about him turning himself in? I wish he would have taken a tropical vacation and thought that through.
Yes, what he did was wrong. I agree. But let's treat him the same way we treat them men who rape children. Let him out with an overworked probation officer to keep tabs on him and keep "forgiving" his backsliding. Around the time he's on his 1000th victim, we'll get serious. That is the way they treat monsters who molest children - sometimes thousands of children.
But on a more serious note, I do agree with you that it's wrong for this man to have killed the monsters. The state should have done it. A mandatory death penalty for anyone who rapes a child should be the absolute minimum. If the state was doing it's job this citizen would not have been pushed into a life of crime. ( Well, if he gets out soon enough, a "life of crime".... I would hate to see the system finally work - and this man only get one chance to commit his brand of crime. Opps, sorry, I mean I would hate to see him not have a chance to be rehabilitated and released after he had paid his debt to society)
