Of course, we all want to live peaceful lives and be free from our baser instincts, but the entire society that allows you to live a "peaceful life" is based on exploitation and war. Just because you don't see it at home doesn't mean you don't profit/benefit from human violence and exploitation.

As for my comment on "monkeys":

1. Larger primates like chimpanzees are known predators that hunt and consume smaller monkeys, specifically targeting babies

2. In the famous Gombe Chimpanzee War (https://en.wikipedia.org/wiki/Gombe_Chimpanzee_War), a once-unified community split into two factions; over four years, one group systematically hunted down and killed every male member of the other.

3. In captive or introduced settings, groups may relentlessly bully "outsiders" who do not know the social norms, preventing them from eating or resting.

4. Non-lactating females may steal an infant from its mother and refuse to give it back, holding it until the baby dies of starvation or dehydration.

"Insulting to monkeys" is only an idea when you anthromorphize monkeys from the actual animals they are to something like Rafiki from Lion King. Nothing is insulting to monkeys because they don't understand the meaning of insult or care about it. They're raw animals and so are human beings.

If you look at the world around you today and think "yes, this is the result of people wanting to live a peaceful life" then I would say you're not being realistic.

Chimpanzee behaviour is chimpanzee behaviour.

Aspects of that behaviour appear in the behaviour of other primates, but not all primate groups have identical behaviours.

Chimpanzee behaviours also vary by troop and circumstances, just as might be expected from social behaviours.

Such behaviours _exist_, but they may not in fact be optimal, inevitable, etc.

Perhaps chimpanzees behave as they do 'cause the bonobo's didn't invite them to the cool parties.
