People die, though not as much in children's cartoons. Very few people actually died in Batman: The Animated Series; the first character to be killed on-screen was Kyodai Ken in "Day of the Samurai". This list only includes murders and on-screen deaths, as by the time of the Legion of Super-Heroes, all earlier characters would be dead.
