D, no kid who is raped will ever reach full potential. The full and happy lives you mention will only be a shadow of what might have been. The rapist is taking innocence and making it ugly. The rapist needs to die to ensure that it never, ever, happens again at his hands. No one can guarantee that life in prison really means life. IN fact, many prisons activily protect pedophiles as they are targets even in jail. Better to simply isolate the nut long enough for the appeals to play out. Then shoot them in the back of the head and throw out the trash.
