DC either needs to tone down the joker (and other similarly extreme villains like Zsasz, Bane, Zod etc) so it makes sense that Batman, Superman or other heroes don't kill them because they're just that evil. Or bite the bullet and kill them off. If not for good, then at least for a decent while so people can at least come to miss them.
As of right now though, characters like Joker and similarly edgy villains are overused, brutally nasty, and overexposed, and their mere existence breaks any internal logic for the DC universe.
