These roots you profess as being our core are more modern than you think in terms of our overall history as a people. - For waring more complicated and denser societies were required than our hunter gatherere tribes of old

- For Pillaging, and power grabs, jealousy, envy individual ownership was required that didn't emerge until we settled down with farming anywhere at 10,000 bc

This too did not happen until we started settling down and consuming all the local resources until they ran dry. Hunter gatherers foraged from larger areas of land with lower population density like wolves or other big predators of today and in a more sustainable way. I'm sure as tribes prospered and grew they split off exploring for greener pastures. One could argue why they couldn't just have a conflict with their neighbours, it's because beyond a certain size tribes tend to be very violent and dangerous governing structures for their constituents. That's the reason why we don't see geographically contiguous tribes beyond a certain size and they usually move to a more chieftan structure of governance.

I think all of this is a round about way of saying, I don't think there are innate, universal, roots that humans are bound by. Beyond our mammalian firmware, and human firmware, most of the rest would be a software programmed through your experiences with the world, that's why there is such an expansive manifold of how humans can live and behave for better or worse.
