When the wolves were created they were created without a soul, animals, killer machines, ones that go on killing spree with nothing to hold them back. The gods regretted their decision to create the wolves, they were rogue, they had no loyalties, nothing to stop them from burning the whole world, they needed a soul. The gods couldn't give the wolves a soul, they refused to kneel down, and their souls were as dark as their dark lusts. The gods forced the wolves to their knees, giving them souls in the shape of humans, kill the soul and die, hurt the soul and feel agony, the souls are to be saved, and protected, no more killing, no more attacks, they are forced to take care of their own soul.
