None of which seem very compelling.

But this happens in observed chimps and baboons too. Once the alpha male claim his territory and have gotten rid of the competition, he also goes into punish mode of any female who does not fall in line with his rule. That is usually the only reason, if not then, most of the time females are hurt.

Chimps try to hide it but they have their own barbaric customs, too.
