Not to mention they are stated to have pooled all their money into this one final attempt at beating Batman. By the time of the Golden Ending, every single one of the major villains in the entire franchise are either locked up or dead, minimizing the chances of any future break-outs or team-ups (the latter didn't matter much anyway - the Villain Team-Up that received so much attention in the advertising was largely abandoned). Even though/if the Batman died, he won.When all of this is considered, that he appears to have died and come back, doesn't that remind you of a certain someone.? Looking at the Scarecrow proves this, with his deformed face, his staggering walk, his barely-visible body, he genuinely looks like a person who died, rotted in the ground for a few months, and then suddenly started moving again. It was said somewhere that the concept behind the Scarecrow's new look in Arkham Knight stemmed from the idea of a living corpse, someone who had died and come back to life, but in the time between had rotted and decayed. A small clue to the Arkham Knight's true identity comes, oddly, from the Scarecrow's design.Not only is this a Call Back to the previous games that featured Joker singing during the end credits, but also one of the plot-lines is Batman reconciling with the fact that there may have been a deeper connection between the two of them. As the Joker's body is cremated, the song "Under My Skin" is playing.
