Have you ever heard of the many female serial killers? Women have within their humanity the same propensity of evil including murder as men. I would say they less inclined on average to react suddenly with murder, but it still there.
There are many videos on social media of Karens and other women slapping people or fighting. Humans as as species, not males as as a species, are violent, self centered and base. Mental issues and society issues cause most of these shootings as well as much of the violence in America. Not gender.
