Sundering stuff established in the Q&A

[Brinne]

To me, her reaction says clearly how she feels. The fact that a world, which sought to remove suffering and succeeded, ended up damned as well hurt to hear. If she always sought a world where hardship and struggle existed and proliferated, and was more excited or appealed to by that world over her own, then hearing this would be a confirmation of that worldview. Not something to feel sad about or despondent over right?

Venat does not take any joy in the prospect of causing destruction or destroying her world. Again, she thinks in the abstract, of an intangible sense of "beauty" that can only be sparked by "in deepest darkness, find light everlasting." That being said, she's willing to go ahead and do it on her ideological basis, because she thinks that's the proper way for people to live - to "become strong", again, "find true happiness." She doesn't relish the idea that the people she knows are headed down a bad path, or that she has to cull them, but more tellingly, she accepts that premise. I think that the fact that she takes, again, a two-sentence description as the basis of which to destroy her current world speaks to a confirmation bias.

The conversation with her at the observation facility suggests this as well. When she discusses the world she currently lives in, she doesn’t lament its current state, rather she expresses an undying love for it and it’s people. One born of a fundamental faith in humanity’s strength and virtue. It’s only after everything with Elpis, and the Final Days, that we see her speak of the Ancients and their inability find a way forward in their current state.

She actually does lament its current state.

On Hermes, Venat says this:

I understand his anguish after a fashion─my own refusal to return is in opposition to the world's established order.

She relates to his desire to oppose the world as it currently exists to the extent of anguish. She does go on to say that she still loves the world, and wants to save it, but of course - Hermes's anguish led him to a subconscious wish to destroy the world. Venat's led her to wish to change the people on it.

The cutscene where Venat hears about the WoL's adventures and their world, and then talks about her own sort of strange, vaguely-defined divine revelation about the correct way to appreciate the beauty of the world, is also very interesting in light of Venat's decisions:
