Yeah, so much better to have 90 % of males killing each outher and utilizing tools such as gang rape to preserve their genes. 10 % would have massive harems and would do whatever they can to control the 90 %, so they won't rebel and kill their leaders and warlords.

Monogamy and marriage is a trait of a civilization. Every man will pair with a single woman, and produce offspring together. And female sexuality is heavily controlled in order to prevent them from having preference to the rich and the powerful.
