How Joker's Return Would Impact the Batman Universe

If Joker sincerely accepted Batman's offer of rehabilitation at the end of Batman: The Killing Joke, it would be a positive turn of events for both characters. Batman has always believed that there is hope for even the worst criminals, and if Joker were to accept his offer of rehabilitation, it would be in line with Batman's principles of justice and redemption. However, it is important to also consider the possibility that Joker may not stay true to his word, given his history of deception and unpredictability. If Joker were to relapse or continue his criminal behavior despite his initial acceptance of rehabilitation, it could be a disappointment to both Batman and audiences alike. Ultimately, it is up to the writers and creators to determine the direction of the story and the characters, but the idea of Joker truly seeking redemption would certainly be an intriguing and hopeful development.
