In literature, indignation functions as a vehicle for expressing a burst of righteous or personal anger, often tied to moral conviction or a sense of injustice. Authors use the term to highlight both public outcry and internal emotional strife. For instance, in works dealing with political and historical themes, indignation underscores the collective discontent of a people, as seen when popular outrage erupts over controversial measures [1] and when an entire nation feels beleaguered by external threats [2]. In contrast, literary characters sometimes experience indignation as an inward, burning passion that clashes with grief or despair, mirroring the internal conflicts of personal morality and justice [3], [4]. Overall, indignation emerges as a transformative emotion that both illuminates and propels narratives of ethical struggle and societal critique.
