if i was the joker id just get a restraining order on batman and superman whataere they gonna do? break the law? then theyre no better than me, a cold blooded murderer. and this would 100% work, because superheroe movies have the shittiest takes on ethics since fucking kant
it wont work on batman. hes already breaking the law by doing vigilante justice and assaulting people with mental disorders. hes acting as judge and jury, leaving the scraps for the cops to pick up. it would only work on superman who works closely with the cops to make sure the right amount of justice is delt
