Yes, good job. Now tell me... Do the movies frame this as a good thing? Or... maybe... the whole point of his entire ten year character arc is that he learns the error of his ways? He changes from a selfish jingoistic narcissist into a compassionate leader and mentor who eventually sacrifices himself to save others.
Maybe one day you'll have some character growth too and watch the second half of a movie.
Sure, if comics were real we all know Gotham would be better off if Bruce Wayne would focus on philanthropy instead of dressing up like a bat but no one would make a movie about that because it would be boring.
Sounds like comic book movies aren't your thing but generally when your story introduces problems like a purple alien guy with a genocide glove the right answer actually is to put on a robot suit and shoot lasers at em.
