Game is called World of Warcraft. So, war is the premise of the game. Personally, I view war in terms of how can I crush my enemy in the fastest and most complete way possible while utilizing the smallest amount of resources and losing the least amount of troops. I would say the side doing that would probably win the war.
If you are talking about who is doing the nicest things during a war, you are probably talking about the losing side. Let the merits of who is right and wrong be written in the history books. By the victors.
