So... damn near *anything* is possible in the DC universe. We're all in agreement with that, right?

Meanwhile, Batman's narcissistic handwringing over his "code of honor" has conveniently let thousands of innocents die, just so his psychopathic playtime buddy can stick around.

I want to see an arc where some super-scientist or uber-psionic gets fucking sick of this and just performs massive, non-con psychic surgery on the Joker to FIX him.

Naturally, the premise is that Bats decides it's the surgeon who has to be hunted down and punished. The B plot is that the Joker is reassimilated into society and EVERYTHING'S WORKING OUT FINE until some busybody crusader decides to restore the status quo for the usual pseudo-humanist "BUT HIS SACRED FREE WILL!" reasons.
