. . . she went and fetched him wine to make him amends, and paid for 't out of her own pocket; for, to give the devil his due, 'twas said of her, that though she was somewhat too free of her favors, yet she had something of Christianity in her.

In "Don Quixote," Cervantes uses the phrase "give the devil his due" to acknowledge the complexity of human character, particularly in Maritornes, who despite her questionable reputation, shows an unexpected kindness. This action underscores the idea that even those perceived as morally flawed can possess redeeming qualities. Maritornes, previously depicted as a promiscuous figure, surprises the reader by paying for Sancho's wine out of her own pocket, revealing her capacity for empathy and charity. Cervantes crafts this moment to challenge straightforward judgments about good and evil, suggesting a more nuanced perspective on human nature. By recognizing Maritornes' generous act, the narrative invites us to reconsider our biases and appreciate the multifaceted aspects of character, even in those whom society might readily dismiss as "devilish."
