Well, an entire subspecies of chimpanzees are pacifist, namely bonobos.

I don't know what you've been reading, but it's not so hot. I've
been in a war, and as a conscript too. That is to say, rather unwillingly. Nonetheless, when people are shooting at you you shoot back. What I'm talking about is that a band of chimpanzees will take a decision to "ethnically cleanse" another group and then conduct a war to that aim over a considerable period of time and involving what obviously constitutes deliberate planning. The other group, if they lose, may be forced out or exterminated.

My point is that the fact we can and do watch such material indicates there is no built-in aversion. There may be enculturated or socialized aversion, but that is not the same thing.
The whole point is that spawning characters with "inbuilt aversions" is not supported by the arguments made.
