Which Venat answers

Poorly, in my opinion. That speech of hers you quoted is very poetic, and also completely meaningless in the context of the circumstances at hand and what she is doing. Just from the outset, nobody is perfect, none of the races we encounter including the Ancients, they're all on that "never-ending quest", and yet the Ancients are supposed by Venat to be a hopeless dead-end that must be replaced by the Sundered. The Dragons are also nigh-immortal and incredibly powerful. But Midgardsormr wasn't "swallowed by despair". He wanted to live, and he wanted his children to live, and the race as a whole clearly want to live. With that in mind, one really needs to question whether Venat's answer - More specifically her actions - Were at all justifiable or even reasonable.

The Amaurotines technically already self-destructed.

Rather, they were destroyed. Specifically by Venat. If Hermes was the madman who created the test, Venat was the madwoman who simply went along with it and judged them failures to be extinguished.

Then the leaders of the society when faced with the threat delete chunks of their remaining population to stop it through summoning a god, and when they decide to sacrifice the life they created to get their society back,

Let's say this is something of an erroneous characterization of events.

As I’ve said before, the future that would face the Ancient civilization if they came back would no longer be the same as it would be before, and would probably more closely resemble Meteion’s projection of Ra La. They all come back to life and now have a living god. Do you think their zealotry or their god will just go away? It would change the civilization completely.

The Ancient's right to self-determination supersedes Venat's opinion on their worthiness to live.

Who's to say some of the Ancients who made the sacrifice if they were brought back wouldn't reach the same conclusion?

we don't know how the Anicents would have reacted to the idea that new life was sacrificed without there consent to bring them back

They do and we do, respectively.
