Hegemonic practices of memorialization rely on narratives of heroic, morally untainted resistance, which cast traitors as the aberrant “other.” This paper draws on Simone de Beauvoir’s The Ethics of Ambiguity and historical and sociological accounts of betrayal to trouble this binary and construct a framework for memorializing betrayal in its ambiguity—in relation to the everyday reality of tragic dilemmas that resisters face. I show how attentiveness to the ambiguity of betrayal can help rethink heroic resistance myths beyond the exclusionary logic (...) pitting moral purity against the depravity of treason—and warn against the reproduction of systematic practices of othering in the new political order. The paper develops the political relevance of this theoretical exploration via the example of a South African novel, The Texture of Shadows, examining how its insights into the ambiguity of betrayal challenge the myths of heroic resistance in South Africa.
