[Batman] If Batman ever killed someone, would Joker quit being Joker?

People always talk about Joker quitting if Batman were to disappear, but what if he won? Would he be bored? Find a new goal? Get him to kill him?

More than likely the last one. A few incarnations treat it as a sick game for him, to see if he can goad Batman into killing him. If Batman killed someone else, Joker would either mockingly be hurt and demand to know what made that other victim so special, or just push Batman til he murdered him too.
