How does the joker differ from other batman villains?

The only verified source supplied discusses the 2022 film "The Batman" and its cast, director, and storyline involving the Riddler. It makes no reference to the Joker, other villains, or comparative traits. Therefore, based on the evidence at hand, I cannot provide a comparison of the Joker with other Batman adversaries. Further details would require additional sources that specifically address the Joker character and his role in the Batman mythos.
