Well the issue is they have to eat people or they'll degenerate into mindless beasts and then kill eachother. It's human brains, or extinction. Of course, conveniently there's a moral solution with some demon that can go around spreading the "don't need to eat humans" gene and then it's just the usual struggle of the MC and all the good guys against some powers-that-be that are fucking everyone over because they don't want to let go of their power. And that struggle is won far too quickly, easily, and cleanly given how difficult it was just to escape the meat farm.
>This is like saying the orb piercer is a villain because it's an "asshole".
The orb piercer is just a dumb animal. It has no moral agency. Bondrewd is a human, later former human, fully aware of the unfathomable suffering he causes others, but simply doesn't care. Ozen is your most retarded fucking example. Harsh training does not make a character a villain and is in no way comparable to vivisecting children, chopping out the parts you don't need, putting the remains in boxes of constant agony, making those box children experience the pain of being turned into an abomination via the curse, and then dumping their useless immortal bodies into a hole where they'll suffer for presumably eternity, just so you can take the most direct routes when ascending a big death hole. If that's not villainous to you, you are a subhuman. And on top of that, he acts as an antagonist for a portion of the story. Just because he's not the only antagonist or not an antagonist for the whole story doesn't make him not a major antagonist.
>It's about the journey, not about beating some bad guy.
You don't have a beat a villain for him to be a villain. Do you think the bad guys winning in a story makes them not the bad guys or something? Are you retarded? Because you're saying a lot of retarded shit.
>That's why they leave bondrewd alive to see them off on their way to continue said journey, rather than spending a bunch of time trying to give him his comeuppance.
They leave him alive because it's too risky to continue fighting him when he's no longer acting as an antagonist and they have greater goals. That doesn't make him not a villain, and Nanachi says she should have destroyed the mask for good measure, lamenting how she missed her chance to permanently off the bastard.
Everyone in this thread, talking about this game, ought to be familiar with the source material. Also, the other anon is right. Ur a faget.
