Every person must have some natural violence pre disposition but that needs to be weighed by their ability to inflict it. I could be a super violent guy on a desert island and so never inflict violence. How physically strong you are must come into that which means opportunities for violence go down with physical size. Even if I want to be violent if I'm somewhat rational and don't want to get beat up.

It's not clear to me if women are less predisposed to violence or have on average less opportunity due to average smaller physical size specially compared to men. Though from experience I would say women also seem less pre disposed to violence in the first place.
