This has been one of the longest-running debates in the history of comic books: Should Batman start killing his enemies? He has one of the largest rogues galleries in comics, and the battles he has with them usually results in them either escaping and/or being sent off to Arkham. Now, he does have a good reason for not killing (he doesn't want to turn into a murderer), but Arkham has lousy security, and Gotham is arguably the most messed-up place in the DC universe because of people like the Joker and his ilk. So, should Batman kill?
