Pretty much the only Batman who wasn't willing to kill AND was on the big screen was probably the George Clooney one (Forever, Batman and Robin). Certainly not the Keaton one or the Bale one.There's a scene in one of the Christian Bale movies that has Batman launching missiles at parked cars to get them out of his way as he rides on his Batcycle. Or something like that, where the chances of innocent casualties is pretty damn high. That Batman certainly didn't have such rules, either.
Oh, and of course the Adam West Batman.
