To get more to the point, the theme of XIV thus far has not been one of accepting a harsh reality / truth over comfortable lies. It's mostly been about letting go of the past and moving forward, despite the pain that can bring; every antagonist is driven, on some level, by a past slight they refuse to let go of or forgive, while the main motivation of the protagonists is to create a better future for everyone.
One need look no further than Emet-Selch / Hades to see this; he is the culmination and (to a degree) final boss of the Hydaelyn / Zodiark conflict arc, driven entirely by his desire to recreate the past. He is called out on this by the protagonists at the climax of Shadowbringers and doesn't offer a rebuttal.
