Theory about the prophecy

So, i was thinking about how to prophecy says that a human, a monster and a dark prince will save the world from the roaring. Of course Susie is the monster and Ralsei is the dark prince, but what if Kris wasn't the human the prophecy talks about? Think about it, Kris is trying to achieve the roaring, not stop it. Instead we (the player) are the one using a vessel trying to stop the roaring from happening. So what if the human from the prophecy is not Kris, but the player instead?
