Is domestic abuse innate, or built into us?

People seem to do horrible things to each other, and quite regularly. In other societies, women will burn themselves to death because they are under too much pressure. There are places where women are essentially slaves.

It’s not just women, too. Men seem to feel privileged to bang around their sons when they do something wrong. Physical “discipline” is used in the military and many other places, I’m sure. It used to be used in schools.

Boys and girls get raped and suffer psychological abuse and this results in all kinds of psychological problems later in life.

I don’t get it. Was this always normal? How did it get to be normal? Is it a relic of days when we couldn’t speak and so we had to use physical signs to communicate? Is it innate? Or is it something we learned somewhere along the way, and if so, when?
