A young Elidibus, filled with love for his people, becomes Zodiark's heart. This same young man that willingly gave himself for the sake of his people must then watch the tattered remnants of their civilization tear itself apart, coming dangerously close to completely invalidating all the sacrifices they'd made up until then. So he separates -- or something wearing his face does, at least. The boy that had been Elidibus ceased to be when Zodiark was created, but his earnest desire to see his people through to a better tomorrow, no matter the cost, survived the end of his soul. For 12,000 years he labored, separated from Zodiark, to try and bring the promised salvation to his people. For 12,000 years he watched Emet-Selch succumb to despair, Lahabrea go mad (or madder, as the case may have been) as a result of using himself up, and the fragments of those he'd once known and loved be born, live, and die over and over again. Then, when he is the only hope left for his people, he takes on the form of his best friend--the WoL's heroic past self--and marches into a battle he knows he can't win. He even regains the lion's share of his lost memories mere moments before being sealed away for (what both he and we) at the time believed would be functionally forever.
Dude goes right ahead and gives up any chance he might've still had at a future existence, again for the sake of his star and his people, when the WoL comes to the Crystal Tower again prior to Endwalker's climax. He, without hesitation, gives up the only thing he still had -- his very being -- for this purpose. Would he really have made this sacrifice after any chance of restoring his people was lost if he were truly so one-sided in his thought processes? With Zodiark dead and any hope of bringing them back slain with him, he could've simply abandoned Etheirys to its fate. Instead he chose to see his people's desire to save Etheirys through anyway.
