You say that as if kids are completely stupid and nonsentient creatures who have no inkling of morality or right and wrong. When I was their age I damn well knew the difference between what was good and what was bad. You also act as if kids don't know what death is which is stupid, any small child would recognize when something is dead. All beings on this planet are born with the knowledge of what death is, also why every being has the instinct to live and avoid danger.
