There is no universal "evil" or "band". Everything is context sensitive. Is killing evil? In some contexts, yes, in others no. The issue is a lack of context in affairs on the other side of the world, in a culture and the lives one has no knowledge about. To levy moral supremacy over others without an attempt at context is what starts wars and disagreements. Take this thought experiment on the importance of understanding context: If i walk into a room and levy my supreme morality by shooting you in the face because i Just saw you shoot a man would be a crime, because perhaps I did not witness the context from 5 minutes earlier of that man shooting another man (which is why you shot him in the face, and ultimately why I shot you). Who's right? Who's wrong?
