Some do it to train them, others do it to set the record straight. Why they do it is not worth a discussion - how to stop them from doing it certainly is. Aside from the physical disabilities, they make one mentally disable, prone to attack, and suicidial. As far as I think, it's a chain of reaction (my father beat me - I beat my son - my son beats his son) that won't go away until they realize that it has done no good to anyone. By using these methods, we're putting the future of our children at risk. Trust me, we are only making them slaves by applying torture.
