She's basically deuteragonist of the story, if she starts murdering indiscriminately, then there's no reason to care about her story except hoping someone will manage to kill her off soon, which obviously won't happen. Why would I want to watch the adventures of a murderer?What, you mean to tell me the people eating monster actually eats people? I'm shocked. Shocked I tell you!
Jokes aside, I hope it is not a red herring. I'm tired of declawed monsters in media.
