Vol4 Ch16: The face of God and Artificial Unintelligence
The reason that humanity's personalities and willpower seemed foolish and inferior was due to an issue with their perspective.
From the eyes of higher entities, Negary's current actions might also seem foolish and inferior.
But that didn't mean that humanity had no redeeming qualities, there would always be elites in a group, and even if they weren't elites, there would be those who desired to better themselves.
This was how Negary was born, he had and would always continue to grow towards perfection, he would discard everything useless to continuously improve and continuously change himself. He embodied the will that desired betterment in all living lifeforms, an entity originally born from a human.
