Capital punishment FTW. As soon as you deny a human being (or an animal for that matter) their dignity and right to life you should be treated with the similar level of pain and hatred that your victims endured.
OK, so suffering in prison is good, but I still say bump the little cunt off, so we don't have to pay for his upkeep. Same goes for all the other Ian Huntleys and John Venables of this world.
