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

[Brinne]

I always found it very...troubling that Venat spun a narrative to her friends and believers that convinced them it was worth permanently killing themselves for the sake of her ideals when they didn't even have the full picture of what she intended to do, just that Zodiark needed to be stopped for what they felt was for the good of mankind.

There's a whole conversation to be had (and has been had!) about the really confusing continued choices of the writers in how they portray Venat and her decisions in the post-6.0 material, if we're seriously meant to think of her as good and having absolutely no other choice but to commit (reluctantly, with great sorrow) the Sundering. I mean, this is a big project with lots of writers. Maybe they're not all on the same page on how to approach the character and her actions, either. They've acknowledged they didn't have the Ancients or Amaurot conceived when first coming up with Hydaelyn vs Zodiark, and that they didn't have dynamis or Meteion conceived when they first came up with the Ancients and the Final Days. It just all feels very, very messy. A lot of the ominous buildup regarding Hydaelyn in the 5.x patches was just completely, unceremoniously dropped without further comment, too.
