If she only killed people we didn't know or didn't care about, such as in Zante's example... it would be a pretty shallow book in my opinion. The casualties can't be only nameless and faceless. The fact that you're so worked up over that particular person's death probably says more in her favor than not. She hit a nerve and was evocative. I think that's a good thing and I doubt I'm alone.

I would not have cried had some random (SPOILER)house elf from the kitchen of Hogwarts had died. But I did cry when Dobby died. It was a blow, because I'd grown fond of him.
