i think your just overexaggertin bro like author loves to troll uruma at the end and reo and kawana are just bitter vigilanties. Uruma conisders himself evil so your opinion is kinda pointless
like uruma failed to save most of them bro. He blames himself bro uruma is one of the six people of the cross so it was obvious he was never gonna get a happy ending is what i am saying also killing one guy still was enough to damn himself
