In Cormac McCarthy's "No Country for Old Men," the quote questions the value of rules that lead to undesirable outcomes. The sentiment implies that adherence to a principle is meaningless if it results in failure or distress. It challenges readers to reflect on the effectiveness of guidelines and whether they serve a constructive purpose in life’s complexities.

This thought-provoking idea resonates with the broader themes of the novel, where characters grapple with moral ambiguity and the consequences of their choices. It suggests that rigid adherence to rules may not always yield positive results, urging individuals to reconsider their beliefs in the face of chaos and unpredictability.
