If your first and only answer to correcting bad behavior is violence, then how does a child learn to use anything but violence to solve their own problems? And if you violently attack your child for the smallest infractions, how do they learn that some things like rape, murder, war, etc., are more wrong than a simple lie. And what incentive do they have to tell the truth about anything they do wrong so they can learn from it, when they’re going to get beaten no matter what. Better to risk lying for a chance at not getting beaten than to tell your parents you made a mistake and get beaten for sure.
