If that's the standard, I guess the sundered need another round of sundering then
Let's see, the Ironworks of 8UC who risked the whole word to dissappear. The Eorzean, Ala Mhigans and Domans who's willing to kill conscripted soldier to take back their lost freedom instead of "moving on". People in general who went ahead with their revenge for their loss (e.g estinien killing nidhogg, etc.). And many others. In fact, the sundered are more prone to violence than the unsundered.
As I've said before, we use our standard as mortal to unfairly judge the Ancients. We say "those lives have been lost, move on", because in real world, there's zero chance people coming back to life. That's not the case with the Ancients, probably. They have the means to bring back those they have lost, it's not a zero chance. You're telling me that we won't do the same should it's also the case for us or the sundered?
Ah yes, venat is so deeply empathized that she chose to not tell anyone about the final days, and prefer being vague as hell even when confronting the Ancients regarding their ""mistake"".
