The Killing Joke, one of my favorite Batman stories ever, stirred a bit of controversy because the story involves the Joker brutally, pointlessly shooting Commissioner Gordon's daughter in the spine. This is a no-holds-barred take on a truly insane criminal mind, masterfully written by British comics writer Alan Moore. The art by Brian Bolland is so appealing that his depiction of the Joker became a standard and was imitated by many artists to follow.
