This is basically the story of the history of human beings, and of our close relatives, the chimpanzees. Escaping these (apparently) hard-wired behaviors is what education is for; humans don't have to act like animals. However, this is what humans revert to when education is dismantled, and when group-identity themes are forced on them - tribalism, nationalism, sectarian religious fanaticism, identitarianism, etc. For example, Machiavellian types have long understood that whipping up religious fervor is a route to political power if they can be the ones who direct that aggression, and this can be applied to any religious organization, and similar in-group based ideological movements as well (communism, fascism). It's particularly illustrative when a major religion is split by internal divisions and the two groups turn on each other with remarkable levels of savage violence, as with the Protestant-Catholic wars that raged across Europe for several hundred years, or the Sunni-Shia schism in Islam, a conflict that continues to this day and which is characterized by things like suicide bombings targeting mosques and so on. Typically you find the leaders of the various groups are political actors who work hand in hand with the priests/ministers/clerics/rabbis/preachers/ideologues to gain and consolidate political power, which, surprise, leads to the accumulation of wealth on their part. This was also a major justification for colonial European expansion in the Americas and genocidal attacks on native American populations (who, it must be said, also went to war with each other on similar grounds, see the Aztec Empire). It's basically similar to in-group/out-group conflict in chimpanzee tribes, which is not surprising as chimps and humans share a fairly recent common ancestor. https://en.wikipedia.org/wiki/Gombe_Chimpanzee_War https://en.wikipedia.org/wiki/Gombe_Chimpanzee_War During the four-year conflict, all males of the Kahama community were killed, effectively disbanding the community. The victorious Kasakela then expanded into further territory but were later repelled by another community of chimpanzees. Forcing members of groups who hate each other to work together if they want to survive could be a way of ah, re-educating them... For example, take two such people, put them in a leaky rowboat out in the ocean, give one a paddle and one a bucket, and see if they can make it to shore. If they use their tools to attack each other instead of to cooperate, well... good riddance.
