[Batman] What's the closest Joker has gotten to getting Batman to kill him?
gpt
Just after Jason Todd died, Bruce Wayne considered killing the Joker, did in fact leave the Joker on a crashing helicopter, and wasn't sure if the Joker was alive afterwards. 

Superman arrived shortly after the crash and Batman asked him to find the Joker's body.
