So I've not really read the comic books, but I've seen every movie and TV series and the one thing that sticks out in those to me is that almost every villain could have been stopped by Bruce Wayne (not Batman) if he stopped dressing up like a bat to beat up low-level thugs and took some time seriously examining his own companies. Either safety issues created mutants, or the oppressive culture drove former employees insane/radicalized them. The only person within the DC universe that sees this is Alfred, and Bruce never fucking listens to him.
Even a bit less than that, "eagles" aren't affiliated with the war and it's own neural third party. Whereas Wayne is in the same conflicts as Buttman. The most logical conclusion is that it's just a hobby of a billionaire, an activity that does not involve reaching some goals, like less crime or helping people. Perhaps there is some sort of (rubber?) kink in there too.
(The above is mostly a situational joke that evolves from comic books early era - they needed a themed costume & a personal identity. And physically fighting crime was at the time seen like a "good solution", and being super rich was romantic/good/attractive. Im also aware how much with how little to initially go on the later comics expanded on these issues & made them more realistic/Bruce a good person. Imho the best argumented reason for Batman & Bruce to exists within their universes are supervillains with superpowers, 'patrolling the streets' is just weird.)
I mean, yeah. It's certainly more fun to see him dress as a bat and beat people up. Imagine reading a graphic novel of just business meetings and shit. lol
Bruce actually does know some magic, but he doesn't trust it to not backfire somehow. Basically, he knows enough about magic to know he shouldn't fuck with it.
There's curses, evil "leaking" from a evil bat god contained under the city, the semi illuminati of the court of owls, the lazarus pit undoubtedly leeching into the water supply and crazying folks up a bit, and the asylum likely being haunted.
Gotham is quite literally cursed to be a shithole. I think theres even a joke at one point that according to all statistics it should be doing better than Metropolis but isnt.
