I believe men are naturally more aggressive than women, but women tend to be more dangerous because the system makes it too easy and too tempting for women to financially destroy their husbands, make false accusations, etc. If men could earn fortunes simply by knocking up and breaking up with women, I'm sure they would do it. If they could get their annoying girlfriends arrested by beating them up and calling the cops, I'm sure some of them would do that too. They would probably, on average, do it more often. But they can't, so you mostly only see women doing this. Most people are capable of terrible things under the right circumstances and with enough temptation. The aggressive tendencies that men typically demonstrate probably makes them, as a group, a little more likely to harm others, but women are probably not far behind when it comes to how willing they would be to destroy another person for financial gain, revenge, spite, or just for the lols, if given a safe and easy opportunity to do so. The ease at which women can do this to men and the financial incentives the system gives them are the causes, not some difference between how men's and women's minds work. Their behavior doesn't reveal a horrible truth about women, it reveals a horrible truth about humans.
