I've thought about it before, when talking about the death penalty to people, whether bringing it back in is really the right thing to do? And I still think it is, but I think it should be used solely for the murderers of children. Killing a child IMO is the worst crime anyone can commit, it's completely unforgivable and as I said before I think those that commit such crimes forfeit any right to be considered a human being and do not deserve any human rights once they've been found guilty.
But that's just my opinion.
