I do think that trying to be so binary about Zodiark and Hydaelyn is a fool’s game since they are written to not be viewed that way. Let's take a step back and understand the ancient point of view towards the final day by taking a look at the side quest “Debate and Discourse”
Loquacious Amaurotine:
“As to the matter of what subject we shall debate today, I propose the recent calamity which has befallen our friends across the pond. What say you?”
“The singular point of contention is, of course, whether or not Amaurot should intervene on their behalf.”
“I believe we should. The scale of the disaster which threatens that distant metropolis is of a scale heretofore unseen, and so equally considerable resources must be committed to counteracting its effects.”
At this point we can infer three things.
-Amaurot is NOT the only civilization in the unsundered world
-They are one of if not the most powerful beings on the planet
-This calamity which we figure out is the beginning of the Final Days has never been seen up to this point in history
This is the viewpoint from someone who agrees with interventions. The counter point is-
Amaurotine Firebrand:
“I disagree. The scale concerns me less than the nature of the proposition itself. Who are we to unilaterally intervene in the affairs of those half a world away? Are we to be the saviors of one and all? Such arrogance may well lead to our own downfall.”
Though Amaurot has God like powers this guy believes to not intervene. Not out of a holier than thou attitude towards others but due to the idea of sovereignty.
It’s kind of the same idea of why Superman won’t kill. If they cross that moral line how easy does it become to blur everything else they set upon themselves. If Amaurot decides to play world police now how is that going to shape the world in the future?
No one likes being told what to do so having demi-gods interfering in your daily life telling you what is and isn’t correct doesn’t sound rad
At this point the WoL can respond in two ways. By dropping Louisoix’s favorite quote.
“To ignore the plight of those one might conceivably save is not wisdom─it is indolence.”
Or instead with the more jaded answer of-
“We cannot save everyone. Sometimes, it is all we can do to save ourselves.”
Picking either option leads to the Loquacious Amaurotine citing that attempting to save these people could be a perfect opportunity to test their new creations as “What benefits Amaurot benefits all creation,”
And the Amaurotine Firebrand retorts with
“How readily you cede the moral high ground! Was not our young friend's point that we have an ethical obligation to aid those in need? Yet not only do you instead elect to focus on the benefit to Amaurot alone, but you also deprive our distant neighbors of the agency to determine their own fate!”
