What's the point with that quite lackluster story in Endwalker?

[Theodric]

Venat isn't really making the best of a bad situation, she's the reason the situation escalated in the first place. Hermes may be responsible for Meteion, yet Venat was the one who deliberately stood by with knowledge of the problem and refused to speak up and then when her people sought a credible solution she wiped them out through a deliberate act of genocide, eugenics and racial replacement. Furthermore, she deliberately spared Emet-Selch due to the Ascians playing into her plans - essentially putting all of their actions upon her shoulders as well.

If it were the Sundered who were set to be the target of Venat's actions then she would would be considered an outright villain with an insane, flawed plan. Both the game and many Venat enthusiasts (when they're not resorting to insults or calling for anyone critical of her to be banned, sexually assaulted or killed...) insist that her way was the only way despite there being absolutely no evidence of that being the case. It's a ridiculously convoluted plan that only worked due her eventually opening her mouth and telling the Warrior of Light and the Scions what the root of the problem actually was - something she very easily could have done back in the Unsundered world by not acting as a saboteur.

More than anything, though, the game insisted for over a decade that acts of genocide were never acceptable no matter how complex or sympathetic the reasoning behind them happened to be. For it to suddenly be something worthy of praise on the basis of it indirectly benefiting the 'good guys' simply shows that the game's protagonists don't actually have consistent morals.

At the very least, I think that we should have witnessed something like this from some of the Scions:



We're supposedly going to see the Scions be divided over something tied to Tural during Dawntrail though I doubt it'll be anything nearly as heavy as the Sundering so it'll likely just be performative.
