No, they see all sundered life as being lesser, because it is. They intend to rejoin all life including that 1/4th of their people.In other words, they see the "life" that is not the 1/4 of their people to be lesser beings.
How have the short stories shown that in the slightest? Not the stories, but while we know Azem didn't join either the Convocation or the Anyder, but we don't really know why.and which the short stories have illustrated that Azem deeply disagrees with.
We have no evidence Hythlodaeus was correct. So far as we're aware he had no direct connection to the Anyder, so his statement may simply be what he (or Emet) believed.The motivation of the "dissenters" who summoned Hydaelyn was also mentioned by Hythlodaeus in 5.0.
They say that as immutable as the laws of reality Zodiark wove may seem, they wouldn't serve to forestall their doom, and they their fate would be the same. And Venat says that the Convocation hasn't offered a permanent solution. This seems to me to heavily imply that the issue the Anyder are seeking to rectify with the summoning of Hydaelyn is the selfsame one Zodiark was intended to solve, not merely a similar doom of their people or an end to them either way. After all, Hydaelyn effectively did that herself.that Zodiark cannot "forestall the doom" of the Ancients.
I'm not really sure why you think he should have set out to scour the vast wasteland permeated with energy the Ascians are weak to in order to search for some trace that the two of them hadn't died when he had every reason to believe they had.Which assumes that Emet-Selch is astonishingly oblivious and uncaring about where Mitron and Loghrif had gone, if he didn't check out the Flood of Light in the first place to find Eden, and, considering his much-vaunted soul-sight, recognized Mitron's soul in there.
Why even do that? It'd be all the same if the First was rejoined and he simply reraised their rejoined souls on the Source anyway.
