These are some very interesting takes. I just understood that H and Z were opposites. I know they were trying to revive Z so that they could rejoin the world. (We already had 8 of those and avoided a 9th in Shadowbringers). Although he is seen as bad. It comes down to the ascians playing him out as even worse then he actually was. Also, H was a being that was created out of the wishes of the people to Stop Z, but she was also an ancient. EW left more questions to Z then answers.
