Bruce Wayne's religious beliefs are never explicitly stated in the comics, movies, or other media. However, there are some clues that suggest he may be agnostic or atheist.
Lack of Religious Affiliation: Bruce Wayne is often depicted as a rational and scientific thinker, who relies on logic and evidence rather than faith. He is also known for his dedication to justice and fighting crime, which could be seen as a secular form of morality.
Religious Themes in Batman Stories: While Batman's stories often explore themes of good versus evil, they rarely focus on religious themes. The villains he faces are typically driven by personal motivations, rather than religious ideology.
Bruce Wayne's Personal Beliefs: In some instances, Bruce Wayne has expressed skepticism about the existence of a higher power. For example, in the graphic novel The Dark Knight Returns, Bruce Wayne states that he believes in "justice, not God."
Ambiguity in Characterization: Despite the lack of explicit statements, Bruce Wayne's religious beliefs remain open to interpretation. It is possible that he has a private faith that he chooses not to share publicly.
Ultimately, whether or not Bruce Wayne has a religion is a matter of speculation. The comics and movies provide no definitive answer, leaving it up to the reader or viewer to decide.
