It's much more interesting to have them kill each other. If I kill someone, there's the pain of their death, but that's ultimately the end of it. Rage towards me isn't anything particularly novel, and always seems to level out to its base relatively quickly. When a passenger kills a passenger... It's a much wider variety of reactions. And, depending on the circumstances, those can last a very long time - even forever.
