Yafya unlike Louise is worse

To Louis. Both are famed, beloved, intelligent, handsome herbivore animals who many think would make great Beastars (Yafya already is one while Louis is only highly thought of to be the next). Both also have a certain disdain for carnivores and often do morally ambiguous things to make themselves feared by said carnivores. However, even before his own growth, Louis didn't do anything unfair to his fellow carnivore students and gradually came to let go of most of his biases while Yafya embraces his hatred to a horrific level and loves torturing innocent carnivore animals
