[Batman] What would happen to Joker if Batman just..... stopped?

Title says it all. Joker robs a bank/plants a bomb/ kidnaps some guys all in order to bait The Dark Knight yet once again. He has a pretty simple plan. Do the crime, torture some guys, fight Bats, maybe if he's lucky piss him off/ hurt him a bit, win/lose the fight. ( He technically wins either because insanity and whatnot). But something's wrong..... horribly wrong....

The scenarios.

1. Bats just doesn't show up.
2. Bats just shows up to meet joker says after everything he went through he doesn't give a shit anymore, and leaves.
3. Same as 2. but he actively tries to kill Joker and he notices. Joker now knows Bats is actively trying to kill him in this situation.

different scenarios not based on initial situation.

1. Joker finds out from one of his goons that Batman kills now, and he doesn't look particularly remorsed about it either.
2. Batman just shows up to joker and kills himself right in front of him (I know it's a bit harsh, but let's just pretend the years of trauma and depression finally caught up to him.)

There was actually A comic where he though that batman was dead, and he became sane again. He got A family, and A job. But when he figured out that batman was alive, he gone insane again.

So, he would be an actual person (Again)  if batman stops.
