It's a little more complicated than that. Men do larger number of violent acts, but they are also vastly more likely to be victims of violence in the US (and most places) than women are. Killing is an example. Men do a large majority of total murders, but about four men are killed for each woman. Women kill only 1/8 as often, but women shouldn't pat themselves on the back for non-violence because the female killing patterns line up suspiciously with the difference in strength. For instance women are much more likely to kill with a gun or a knife, and are more likely to kill a family member, intimate partner, spouse, or their children. Speaking roughly, men kill outside the house and women kill inside the house. Not too surprising when most men are much stronger than most women. Note that 3/4 of victims of violence by women are women, and most violence against children is by women. Which tells me, that it's more about size and strength than it is about men being that much more evil. https://bjs.ojp.gov/content/pub/pdf/wo.pdf
