I don't think it's anything to do with testosterone. It's about power, control, insecurity and cycles of behaviour. Females are just as prone to that as males.
Well I don't have any proof, sir, it was just a bold naked assertion about the testosterone. Having said that, females might be prone to those things you listed but they certainly don't resort to beatings with nearly the same frequency as men. Again, I am making an assertion with no good evidence but I feel more comfortable with this one.
