I have been following the stories around each member of the Dark Knights and the Dark Multiverse; and no matter what you said, it clearly proves Batman is a very sick and twisted person. He's essentially as insane as any immate of Arkham Assylum.
Each of the Dark Knights represented one of Batman's greatest fears, being the biggest one the Batman Who Laughs, the result of Batman becoming the new Joker. We know about the incomming of a new Dark Knight, the Batman with Guns, who killed Joe Chill with his own guns and he's basically Batman merged with the Punisher.
However, there's one more fear from Batman that should be explored and that it could actually become something that the Dark Multiverse rejects and join the official Multiverse. What kind of world could it be? Well, an "utopia"... Without Batman!!
Let me explain, imagine a world where Bruce Wayne died alongside his parents, so there was never a Batman in this world. But in this world, the absence of Batman has allowed the world to become an utopia. How?, well, for start, even without Bruce Wayne, Gotham still has a Dark Knight: Katherine Kane, Batwoman. She ends up inhereting the Wayne's fortune as the closest relative to Bruce Wayne, and she starts a journey similar to Bruce's, but way different. For start, his militaring training make her erase the "No Killing" rule of Batman; which allow her to eliminate permanently all the psychos from Gotham, and eventually, all criminals. Gotham becomes a safe city without crime thanks to Batwoman; it eventually becomes the base for the Colony and becomes a force of good around the world. Everyone in the Bat-Family ends up joining the Colony and have happier and better lives than with Batman. The Justice League gains a lot of public support without the paranoia of Batman, with Green Lantern taking his role in the Trinity. Because of Batwoman and the Colony efficiently eliminating the criminals, the Justice League's wins over their enemies and help the world to become an Utopia.
And how is this Batman's biggest fear? Because it represents that all the decissions he made after his parent's deaths were wrong, and the world would have been a better place without both, Bruce Wayne and Batman. Interesting, huh?
