[DC] Would the Joker have any issues killing a Joker from another dimension?

Some dimensional rift thing happens. Would he have any qualms murdering a different version of himself?

They'd be absolute besties until one laughed wrong at the wrong joke, and it would still be on the surface completely fine, but they would rapidly go into legendary levels of resentment, and sooner rather than later both would start planning to kill the other, and watching each other with rapidly escalating paranoia.

The moment whatever lunatic plan works and the multiple Jokers get Batman in a position to murder him (and a Sinister Six of Jokers would absolutely get him in that position), at least one of the Jokers if not multiple would immediately try to murder the other Jokers, because who the fuck do *they* think *they* are, to get in the way of *my* dealing with Batman?
