That monster is wayyyyy too judgy for a guy who literally eats people. Just eat some cow meat, dumbass.
(I'm joking, sorta. It was an interesting plot, but it was hard to take the monster seriously as a "judge" when at the end of the day Bell was making the same choice he did- kill a bunch of people to preserve the life of one, except Bell was doing it for her sister and the monster was doing it for himself. I suppose that adds a bit to the tragedy, but I wanted pretty badly to at least try fighting back against him instead of just surrendering one of the two people.)
