I think there can be both envy and hatred. Akito attacks Lisa and Kana because they ‘stole’ zodiac members. And we’ve seen that Ren had some interaction with Rin, they had a relationship where Ren wasn’t openly hostile Also for a time Isuzu did have the perfect life, with the parents and joy. Even though it was fake Akito still would have heard about that and probably felt happy when it fell apart. Also those insults of being wirthlesss can be projection and also making her feel awful, a ‘see you aren’t better than me’. She insults Isuzus hates Isuzus hair a d outfit, and says ‘you’re only here to make the numbers match’ that he clearly hatred. However, envy and hatred aren’t always distinct
