Throughout literature, "deceitful" consistently conveys a sense of moral corruption and hidden duplicity. In one instance, irony is employed when a character laments that even humility is not exempt from artifice [1], while in religious texts it is a recurring descriptor for those whose words and judgments betray their true intent [2, 3, 4, 5]. The term is similarly applied to nature and human behavior; for instance, it is used to caution against trusting fair appearances that conceal treachery [6, 7] and to condemn actions executed under a guise of false modesty or cunning manipulation [8, 9]. In narratives spanning from ancient epics to modern dramas, "deceitful" serves as a critique not only of individual failings—such as the betrayal inherent in personal relationships [10, 11]—but also of broader societal and spiritual deceptions that mislead communities and undermine justice [12, 13, 14]. This layered usage enriches the literary portrayal of characters and events, urging readers to look beyond surface impressions and recognize the inherent danger of duplicity [15, 16, 17].
