Batman but he finally gets therapy to deal with his parent's loss and realizes dressing up in a suit to beat up petty criminals is a trauma response and begins to invest billions into healthcare, police abolishment, fair housing, and drug treatment which drastically reduces crime to the point capitalists plot to eliminate him and when the succeed, this prompts the Justice Leauge to go after the industrialists responsible for his death, which give the general populace a chance to seize the means of production and the military is afraid to act because Superman has promised to destroy one military base for every civilian life they take.

That would be a pretty cool story.
@Are0h Only nitpick I have, just because he realizes that his crime fighting is a trauma response; doesn't mean he stops being a master martial artist, with preparedness bordering on the level of future sight. I could see him ether faking his death, or warning the justice league in advance so he could go after these corporations with evidence and as minimal application of force as possible. Although your version is way more exciting, and equally plausible.
