I'm rather partial to Hyth's character, going back to his original introduction in Shadowbringers. I think that he's probably the most grounded of the Ancients that we've met, probably owning in no small part to his lack of magical power. Yet you can't deny that even he talks about real problems from the safety of an ivory tower. When confronted with Hermes' fears about death and loss, instead of addressing the emotion on the table, he goes into an eloquent monologue on what a beautiful concept death is in their oh so wonderful society. Meteion is very deliberately inserted as an uncomfort-o-meter in that scene to show that the Amaurotians' responses aren't empathetic.
And you can't really blame them. They're sheltered godlings playing at being the ruling class of the planet. Addressing emotional distress in others isn't exactly their strong point.
It's extremely difficult to simultaneously extol Emet's actions in Shadowbringers and condemn Venat's actions in a way that is consistent. Especially after the scene in the Ocular where he specifically talks about murder as being merely a matter of perspective, and after he uses that same turn of phrase ('twisted, malformed creatures') to describe members of his own (or 'his body's own') Garlean family. I think he's a fantastic character, and thoroughly entertaining. But I wouldn't entertain any illusions about the long dead and abstract 'principles' behind his actions in Shadowbringers. You can find someone charismatic simultaneously and disagree with their actions and ideology.
If you do want to go with the Frey-themed interpretation on Emet and Venat (which I personally find interesting), it's worth remembering that Venat is an OG convocation member with a lifetime's worth more experience on the likes of Emet and his cronies. Not only does she successfully stage a coup to neuter the convocation's powers, but she also deliberately spares Emet and then spends the next twelve thousand years schooling him in the long game. Poor Emet couldn't catch a break, he outplayed and outmatched. By that interpretation, Emet, Venat, and the Convocation are all of a piece, and we're just lucky that our own interests aligned with the winning side.
Like Yoshi-p stated in the Q+A, it's interesting how different the Ancients are from us as a people in thinking and in empathy.
