Humans can be wonderful and horrible. I don't think gender has that much to do with it, though the media will tell us differently.
I just posted about this in Men Don't Have A Monopoly On Violence - The Myth Of Female Innocence
The idea that only women are victims is a false one. It gets back to the idea we were discussing, that humans are humans and are capable of greatness and deviousness. I don't see it as a gender specific issue.
