The term “requital” appears in literature as a multifaceted concept, often used to denote a response—whether of gratitude, compensation, or retribution—to a preceding act. In poetic and dramatic works, such as those by Shakespeare, it is evoked to accentuate the reciprocal nature of love and duty, suggesting that kindness be met with a fitting return [1, 2]. Epic narratives also employ the term to signify a measured balancing of deeds, as in the grim retribution exacted in heroic contexts [3, 4], while philosophical and ethical writings use it to explore themes of justice and equity, implying that every action carries its own due by nature [5, 6, 7]. This layered use enriches the narrative texture, underlining that the response to an action, whether tender or harsh, is an intrinsic component of the human experience.
