Well if murder was legal I am sure most of the population would do it because there is no reason to get in trouble, but the reason most people do not murder people is because A: it is wrong and B: it is illegal. Sure, people break the law, but they try to hide their crimes to NOT get in trouble, and most of the time, end up getting caught. We banned kickballs in schools, kinder egg surprise, squishy toys, etc. These were for injuries, choking, and unregulated material and those are dangerous but they are not the main output of children death globally.
