I find your gross generalisation to be....gross

Saying the if a child rapist wants to kill the victim then he will is a bit of a circular argument I think. He wants to kill so he does. Well, yes, that's true. But it's not the point is it? My point was that if the rapist wanted to enhance his chances of not being caught and convicted then he should logically kill the child because the penalty for actions in raping the child is the same as his actions in killing the child so he has nothing to lose.
