They have made it clear what the interpretation should be. In this game (not real life), societies who reject suffering would end up depressed and nihilistic. If Hydaelyn didn't sunder the star, they would end up like the third group in the final MSQ dungeon (the one who asked Ra-La to kill them all). They would not even need Meteion to end them. They would ask Zodiark to grant them their gentle death.
