While Batman Returns is arguably the most notorious example of Batman killing an enemy, it’s not the only time that’s happened in a theatrical setting. In Batman v Superman: Dawn of Justice, Ben Affleck’s Batman is so damaged and worn down from his losses (especially Jason Todd, the second Robin) that he has no problem with killing his enemies, be it by gunning them down in the Batmobile or slamming their heads into the floor, and that’s ignoring the Knightmare vision, too. And while Christopher Nolan’s Batman stated numerous times he was against killing, you have to wonder just how firmly he stuck to that rule. After all, there’s that scene in The Dark Knight when Batman drives the Batmobile into a truck being driven by one of Joker’s henchmen and slams the front end of it into the roof of the tunnel. It’s hard to imagine anyone surviving that. Let’s also not forget Bruce Wayne leaving Ra’s al Ghul behind in Batman Begins despite him justifying that as simply “not saving” his former mentor.
