Gal Gadot’s Wonder Woman does not always resort to lethal force in the DC Extended Universe films, but there are several instances when she kills her adversaries. Superheroes killing their enemies is a subject of debate and controversy in both comic books and their adaptations, with Superman and Batman’s DCEU iterations dividing viewers in their inconsistent use of lethal force. For Superman, the desperate act of killing General Zod led to him adopting his no-kill rule, while Batman usually doesn't kill criminals outside of Batman v Superman: Dawn of Justice. Wonder Woman, like her comic counterpart, lacks a no-kill rule but nevertheless only uses lethal force in specific situations.
