I read a similar discussion about Batmanīs religious beliefs once. The best suggestion went something like this: Batman knows there is a God, and has several plans on how to stop Him if He ever goes rogue.
He's the world's finest detective. That's his job to find out. Maybe proving that Jesus never existed or that the Bible is just bs. But he does not need to get involved into religion.
Not that this is THE religion thread BUT - whether or not Jesus existed is not a question. Even people who don't believe in Christianity admit that he existed and did the things he did. They just believe he was just another prophet. And about the Bible - anyone who reads it would realize it's not BS as it has, and continues to prove itself as it predicted many of the things that has happened since its publication.
Batman would not have any control or anything that he could do to fight against God or anyone else near his level. I don't doubt that he could figure out what's going on, or why things occur, but he'd be helpless.
I have heard about the biblical code in which you can predict the future. There's a similar code in Moby Dick! I'm not here to debate on religion but Batman could at least once question his religion if he hasn't done it yet.
So what religon is superman the kyrptonian , did the krypotonians belive in god? I'm thinking not because they were to advanced in science showing they focused their attention more on it then religon. They probaly belived in evolution like smart highly advanced beings would.
Also Superman, Spiderman,X-men , and BATMAN were created by jews!
That's funny that's why you see so many superheroes fighting nazis.
Constantine knew and believed, but hated it....i guess if you had to do God's dirty work and fight Demons and Hell while still being mortal you would hate to believe what you know as well.
