Venat's cutscene. Given that was from her perspective, it goes to show what a low an opinion she had of her people. The irony being she's painted as impartial, but after the events of Elpis cause her to have a crisis of faith she becomes quite biased and is in absolutely in no position to be making life or death decisions especially on a global scale.
Venat is presented with the opportunity for a 'do over' when the WoL tells her that the future she ushered in resulted in 1) the omnicide of original Etheirys, 2) the obliteration of 8 shards including the 13th, 3) the near annihilation of the First and this isn't including the 8UC timeline. We're also there because we have no idea what to do. The Final Days have returned, they're exponentially worse than the first round because thanks to the sundering souls are now so susceptible to the Song of Oblivion it outright destroys them. We're at a dead end. The fact that this knowledge as presented is considered adequate let alone acceptable to determine that the WoL's future was the best possible outcome, especially when she literally never tried anything else, is absolutely nonsensical.Her back was always against the wall, knowledge of the coming demise does not stop it already.
As for Hermes, Venat's reasons for not acting against him are inconsistent with all of the preceding narrative. I don't know what more there is to say about it.
There's nothing morally grey about it and since I keep seeing this reasoning I'm left to assume a decent amount of this community doesn't know what morally grey is. Just because it's a black action and white response doesn't make it grey. What the writers did in EW was undermine every character in the game at the expense of Venat to glorify something that at any other time they would have adamantly been against, in fact, I'd go as far to say that she represents the antithesis of the moral standards put forth by the Scions over the past decade. It was jarring. This isn't even addressing the outright breaking of certain characters, like Emet, who were so grossly manipulated to prop up Venat as a 'good guy' that there was just no taking it seriously anymore.
