And then they all die, except for MC who goes full tard rage, and manages to remove one eye from the main bad guy this time, then he gets stopped by the secret always been there super duper trio that bends metal with their bare hands, and probably rapes babies while eating them for breakfast at the same time, and then he gets to work with the police force next arc, because now they're somehow influencing everything on a global scale.
Oh also, once he finally kills the final baddie, he'll act triumphant that MC turned out exactly like he hoped he would, giving you no change to feel any form of catharsis. Also all the police will die, and 90% of the world's population.
