In "The Castle of Otranto," Horace Walpole presents a world filled with darkness and despair. The quote, "This is a bad world; nor have I had cause to leave it with regret," reflects a deep sense of disillusionment. The character expresses a bleak view of life, suggesting that the experiences have been so negative that there is no sorrow in departing from it.

This sentiment resonates with the themes of the narrative, which explores the complexities of human emotions and the often tragic nature of existence. Walpole's work serves as a reflection on the struggles faced in a tumultuous world, emphasizing the darker aspects of reality that can lead to such resignation.
