وَالنَّظَّامُ: أَنَّهُ لَا يَقْدِرُ عَلَى خَلْقِ الْجَهْلِ وَالْقَبِيحِ

Ignorance here concerns a creature's lack of knowledge; ugliness concerns an act judged blameworthy. An underlying concern is that creating such a state might make the creator ignorant or blameworthy.
The reply first separates two relations: producing a quality in a creature and personally possessing that quality.
