I enjoy how far she'll go to protect whats most important to her, and that really defines her as a character. Murder isnt a good thing no, but life isnt always so peachy. When youre at war who knows what you have to do to protect yourself or another. I honestly have no idea, but i can imagine the decisions to be rough. Not like she doesnt feel anything at all. If you kill someone, theres no promises that you wont regret doing so. It may have been to protect something else, but you still have blood on your hands now. That doesnt sit to well with everyone, even if they seem to appear strong.
