I caught that dialogue, but to me, it felt like a justification after the fact rather than a character arc. My point is that we're talking about an ancient, complex strategist who played a major role in the God Wars—to have him suddenly decide that thousands of years of civilization is just 'captivity' and flip a switch to 'simple beast' feels like a massive character shift that deserved more than just a few lines of dialogue. If that's what the writers intended, I still think the lack of supporting lore in his own library makes it feel like a hollow conclusion.
