D. “I had desired it with an ardour that far exceeded moderation; but now that I had finished, the beauty of the dream vanished, and breathless horror and disgust filled my heart.” (3)
This excerpt encapsulates the transformation from ambition to horror, emphasizing the consequences of the character's desires and efforts.
