Try to survive long enough as one of Joker's henchmen. Then when Joker inevitably captures Batman, and inevitably puts him in a death trap that he fully expects Batman to escape. End the cycle. Pull a gun, shoot him in the face.

Not saying you'd survive the Joker afterwards. But Batman isn't bulletproof.
