I think this not the way to look at war or any species wide behavior. War is a consequence of the sort of social animal that we are. Our ancestors and living related species lived in groups of related individuals. They routinely attacked other groups when they came into contact with them (that didn't happen too often when there were a lot fewere of us). At the same time they were altruistic to members of their own group because this produced more offspring. Hypocricy is a notion that was invented later only after we had morals, which evolved culturally. The ability to think symbolically has made it possible for us to contemplate moral issues. To ask if it is ok to kill other humans who are not part of your tribe.
