@Anreon I have no doubt she's counting herself in as well. She does acknowledge she's a human, herself, after all. Often humans are hypocrites, pretending they are doing bloody deeds for some higher purpose, and thus they aren't really cruel, they are just doing something that needs to be done and they can't avoid it. It's either for their own sanity or to look better in the eyes of the people. Olivia doesn't care at all, which is understandable, seeing who acted as her guardian as she was growing up. She knows humans are cruel and quick to kill, so she does it without hesitation and doesn't pretend it's something else than what it is. Her occasional statements are only there because up until now, she was living alone with the spirit of death, so all of her knowledge was just hearsay and information for books, not actual experience.
