Okay, so women have historically tended to focus their anger inwards and hurt or kill themselves rather then vent their fury on others. But at that point in time women were considered the inferior sex. Unintelligent, weak, dependent on men. Times change and so do people. Women wear trousers, women compete with men in the work place, women sound their horns and shout at other drivers who cut them up in the car.
Some women even enjoy one night stands.
I therefore do not see why we should find it so unimaginable that a woman is capable of the same kinds of atrocities as men. A Rose without her Fred. I think it is. In fact, I think it is only a matter of time. There are violent women, selfish women, women who will gladly do whatever is needed to satisfy their own ends.
