He got more than Michael Jackson didn't he?
I do somewhat like the idea of the research, only through research can we make any corrections. I'd love to eliminate the entire problem, rather than one individual. You can go ahead and execute Pedophile Pete, but there is Pedophile Percy right around the bend. Not to mention Pedophiles Steve, Chris, Frank, Bob, Ricky, Joe, Jeff and every other name you can think of. Plus, if there is something "hard-wired" in them, quite possibly we can rip it right out of them.
There are so many things we have fixed as human beings. Think of the diseases we have cured and eliminated. Think of the things scientists have done, with some money and time, it can ALL be corrected. Don't you trust that perhaps we can fix this as well, eventually?
How many pedophiles have been studied,the chemicals in their bodies, compared their upbringings, etc. REALLY studied. What really makes them do this crap, like really? If you found that there was a malfunction in their growth that caused this, would you be able to forgive? You forgive the fat disgusting pig as soon as you find out he has a thyroid problem, dontcha? Do you think we should kill a person because there was a malfunction in their brains? Um, no.
I'm just playing devil's advocate here, I'd like nothing more than to just shoot them in the head, but it solves nothing. If they can't help but do it, then knowing the punishment being death won't make them stop it either.
