This article does not constitute a scientific argument, merely a hypothesis.

Richard Dawkins in his book “The Selfish Gene” uses the fact that a single gene may exist within many individuals as a potential explanation for altruism. However, when one person is in control of many things, they do not in all cases make them act nicely to each other.

If I were wanting to build a great RC airplane, I might build a few different models. Rather than tie them together with strings such that they might all pull each other and help each other out, I might decide to test them side by side and throw out the lesser models in favor of the better model.

The same argument can be applied to a single gene existing within multiple people. To the extent that that gene wants to exist within as high-grade of a being as possible, it might encourage multiple beings under its control to a competition, and act on the results of such a competition. Both sport and war might be instances of this competition.

Thus violence may be the scientific method of genes.

This differs from the idea of violence becoming necessary due to resource scarcity, such as fighting over mates or food. This is purely about violence for the sake of either death or else diminishment of the loser, either physical or psychological.

When a person loses a competition, their testosterone is known to decrease. This could be one human-level example of such diminishment.

Of course this is pure hearsay, an extremely weak argument with no empirical evidence. Still, an experiment can be designed and run, which I plan to do, which might show whether or not this is possible and under which circumstances it is possible.
