i say kill them, and not only that but I would say to kill them very slowly, maybe even over the course of a week. To me, to rape a child or kill a child is probably the worst thing that a person could possibly do in this world. My stomach feels sick and I become enraged with hatred and anger when I read about things like this. Look at how many child predators there are in the US, Taiwan, Indonesia, Sri Lanka, and the list goes on, these people should not be free to roam the street after a few years in a minimal security prison. And I dont really care if a few innocent people die for the greater good, it is like the age old question "Could you sacrifice a child to save the rest of the world?" My answer is yes, because think of all the other children you would save... Not only that but the percentage of error in this day in age is slim, extremely slim this wasnt necessarily the case 15 + years ago which is why you hear of these rulings being overturned. These five men deserve to die right along with everyone else like them
edit: This is all assuming that these individuals have evidence brought against them for the crime adn that a jury of their peers have found them guilty beyond a reasonable doubt
