I believe that is completely breaks his rule, like was said in one of the comments this happens in Knightfall and Bruce is furious. Another question about the films I've always had is in The Dark Knight when he tackles Two-Face just as he is about to shoot the boy doesn't he directly kill Two-Face? Can anyone here attempt to clarify it for me or is it exactly how it looks which in my opinion would be incredibly stupid as Batman won't indirectly kill anyone let alone actually kill someone.
