Wait, have Bryke and Dimantino actually addressed this? The proof of futility of his quest is his fucking father, did no one point it out to him? Did he just not know he was conceived after his dad lost bending? Was he genuinely expecting to purge every newborn bender until he dies or something, the fuck was the endgame?
I never really thought about it because I hate thinking about Korra, but I actually want to know what they cooked up for Amon's goal if they screwed up his motivation this spectacularly. NOTHING FUCKING FITS WHY IS IT MORE ANNOYING TO ME NOW
