On the one hand, when hundreds of women have turned up dead, someone needs to do something. And if the police won't do anything... I can see where a woman would get fed up. Hell, I would get fed up. It's an ugly thing, but I can see where someone would want to take things into his or her own hands, if there were no recourse through legal means.
On the other, we don't know that the guys "Diana" killed were actually guilty. If not, well, that's not exactly helping things is it?

In any case, I find it very disturbing that two dead men capture the attention of the world and the local police department, while hundreds of dead women get no attention at all. That is seriously fucked up.
