Yeah when Batman sees killing Joker as just as bad as him murdering random Innocent civilians of Gotham, he’s stupid.
Same for Two Face and Scarecrow and all the others. Batman by leaving people to escape jail and murder more each time is not helping Gotham.
I can understand Batman and his motivations, but I think he has blood on his hands, and not just from the crooks he leaves with crippling medical debt.
