Being human means that by our very nature, we possess the ability to change our nature. Just because violence is part of who we are doesn’t mean it has to be a part of who we become.

True, but I'd suggest that to anyone looking at the weight of history, it's far beyond any doubt to make the correct observation that people 'tend' to. Simply sort of hand-waving it away and saying "well there's no law of nature that says it has to be that way," to me is analogous to saying "yeah, and there's no law of nature that says we couldn't build an elevator to the moon, either."

Nature is violence, but its arguably more about cooperation. especially in highly social species like us.

Eh, I'd say this is debatable. I'm not saying cooperation isn't part of who we are, but humanity's overwhelming tendency to indolence explains why violence is often a consideration that makes its way through our minds at the first pass. Most people don't have a respect for the law out of high minded morality or a desire to be cooperative. They obey it because they're afraid of violent social retribution. Human beings are moral scavengers driven by opportunity and prudence, 'more' than, but not exclusively, moral ideals out of a sake of 'doing the right thing'.

It's always easier to beat a child than it is to raise it. It's always easier to steal money than it is to earn it. It's always easier to cheat your way through your work, than to do it the correct way. I don't see that attitude changing anytime soon. But I don't disagree with the core point I think you're getting at.
