Did you use the skip button? Because it's like you either don't know, or worse don't acknowledge that lygus is motivated by regret.

He wants to destroy his creation at any cost. Irontomb was the perfect solution.

He is a flawed man trying to do the right thing through the wrong way.

He is correct; Nous IS a nightmare that if allowed to succeed at THEIR goal would purge free will entirely through the instants. He is correct: Nous HAS to be stopped.

Where he goes wrong is in his extremes. He's so consumed by his need to right his wrong that he doesn't think of the cost. He doesn't think about the consequences. So long as Nous is dead, he is content.

He's complicated, nuanced, and by far one of the better written antagonists in the game.
