Except Batman's saved Gotham and the world a few times. Presumably not being a billionaire would make that much harder. Personally, I think the continued existence of everyone we know and love is worth more than all of Bruce Wayne's wealth.
When someone plants a bomb that will destroy Gotham and Batman defuses and removed the bomb, what has Batman done to the city if you don't think he saved it?
Like, if I save a child from getting hit by a car today is the kid now immortal?
Not like we have any other choice like using nth metal to make more secure facilities.
Oh wait
I forgot
You're taking this entirely too seriously and I'm not arguing over a fictional city with someone who seems to have a lot more invested in this than I do
I have two long boxes of Batman comics. I'll have my fun. You can have your Internet fights.
