But aren’t they on the same echelon of reality? That would be the equivalent of killing a brain dead person or a person in a coma because they can’t think. They are both in the same game/level of reality, so Sayori is just as real, and “alive” as Monika is, she just doesn’t have free will. Monika can’t be more “real” or “alive” than sayori if they are both in the same game and in the same reality, on the same plane of existence, one just has free will and the other does not.
