"Ok. If we're going by your logic. Anyone is allowed to kill you just because they gave a dirty look. If San gave a dirty look at me I am now justified to kill her, regardless if what she had planned to do was malicious or not. Heck, the guard could have been fed up being ordered around and decided to let us free. But we won't know if that's true or not because you killed him. No, instead you would rather act on instinct instead of thinking things through, and then worry about the consequences later."
