In "Don Quixote," Miguel de Cervantes illustrates the themes of ingrained wickedness and selfishness through the character of Ginés. Reflecting the idea that those who are ungrateful often act out of necessity, Ginés embodies a lack of moral integrity. His decision to steal Sancho Panza's donkey demonstrates a disregard for the future in favor of immediate gain, highlighting the ease with which people can resort to wrongdoing when tempted by opportunity.

This act of treachery serves as a reminder of the darker aspects of human nature. Ginés's actions reveal how desperation can lead an individual to exploit others, reinforcing the notion that some individuals are driven by self-interest without regard for the consequences. Ultimately, Cervantes paints a cautionary tale about the perils of prioritizing short-term benefits over ethical principles.
