Tough call. In general, I think these prisons clearly need to be better policed because, it's true if this was able to happen twice then it strongly indicates that terrible things are happening to people who are in for less horrific crimes. So in general, I am very much against vigilante justice in prisons. As has also been mentioned - the men doling out this sort of thing are clearly also violent criminals (before this), so how c a n you applaud it?

On the other hand, I have absolutely no sympathy for this monster, and I agree that nothing they could possibly do to him compares to the damage he must have done to that child before he died. His own son, for Christ's sake. Taking the wider context of the clearly broken prison system there out of consideration: I hope he dies of septicaemia, and I'm glad that he's suffered in the run up to that. There is no other fitting outcome for his crime.
