How should the Joker be Defeated ?

Ok, I don't know if this will make any sense whatsoever but I think what the joker needs in order to be "defeated" is for 배트맨 to stop caring, no matter the cost. That'll drive him to actual insanity. Jokers like a child on a playground at first he's annoying and 당신 hit him back and scream, but the 분 당신 ignore him he quiets down. It'd be like having a piece of himself removed. 배트맨 is what keeps him alive after all. Sorry i haven't really read all the comics so if 배트맨 already did this and failed i didn't know. and in regards to who is a better character, joker win 의해 a mile, theres no competition, he's a real jokester (pun intended)
