I do not condone murder but if the harm you are consciously causing to others is that much destabilizing that the trauma could pass down to the victim's offspring do you deserve to live?
the problem then becomes who is to make that decision
murder is the evil corruption of the natural process of death except for food chain or self defense purposes
pedophilia is pure evil sickness that creates more of its kind (unless you completely repent maybe)
in this case it does sound like it lines up with revenge though
