Same, my biggest turning point from angry rivality into hate was his cowardly nature, he gang had everything: resources, advantage of being older and more experienced, backing of the he clan, backing of the rogues (turned into a cultivator and given powerfull arts that steal qi) and he still a pussy_.To me until He Gang is dead he is worse than Rou. Gaining Qi is one thing and now actively hurting your family and loved one is another. It's why I never understood the hate Rou gets when their are people like He Gang who gains qi easily while making your life miserable. Everything Rou hater says about Rou apply to He Gang and worse is his actively going after your loved one who can't defend themselves.
Instead of getting even more ahead of us by reaching qi sea or trying to get even on a death match, he tries hurting our loved ones and connections on a psychologic war (that he himself loses If you go provoke him instead of attacking) at least ruo even with all his bullshit is still a equal/rival, he gang is Just a clown that will get his meridians burned and his dantian devoured as a supplement.
