Fratricide occupies a remarkably persistent position across the depth-psychological corpus, appearing not merely as a biographical datum or historical curiosity but as a structurally significant symbol of primordial psychic division. Jung indexes it repeatedly in his late theological writings as an emblem of the metaphysical split attending Creation itself: the Cain-Abel narrative signals a disunity inscribed at the origin of consciousness, a dualism that monotheism could never fully absorb. In Answer to Job and Psychology and Religion: West and East, Jung catalogs fratricide alongside the ‘hostile brothers’ motif as one of the archetypal configurations through which the unconscious figures its own internal warfare. Rank, approaching the theme through literary morphology, identifies fraternal hatred as a standard dramatic requisite stretching from Greek tragedy through Schiller, arguing that the biographical absence of a literal brother is compensated by imaginative substitution. Konstan’s classical scholarship, meanwhile, traces how the stigma of fratricide functions emotionally in Aeschylus’ Seven Against Thebes, displacing civic fear onto a specifically intrafamilial horror. Zimmer situates it within the amoral realpolitik of Indian statecraft as one of the routine instruments of political self-preservation. Taken together, these readings reveal fratricide as a psycho-mythological nexus where kinship solidarity, shadow projection, guilt, and the compulsion to destroy what is most proximate to the self converge.
