Within the depth-psychological corpus, murder functions not merely as a juridical or ethical category but as a multi-layered symbol touching the foundations of psychic life, ritual necessity, and the structure of evil itself. Plato’s Laws furnishes the foundational legal-theological framework, distinguishing voluntary from involuntary homicide, prescribing purification rites, and situating killing within a cosmology of pollution and divine retribution. Rohde’s study of Greek soul-belief extends this into archaic religion, demonstrating how the unavenged murdered soul becomes an active, vengeful agent demanding propitiation. Padel traces the bond between spilt blood and the Erinyes, arguing that murder and madness are inseparable in the Greek — and by extension Western — tragic imagination. Jung, in both the Red Book and his commentary on Nietzsche, treats murder as an inner event: the vision of the slain hero prefigures collective catastrophe and signals the movement from one psychic dispensation to another. Hillman re-examines murder through the lens of daimonic calling and the shadow, resisting reductive parental explanations for extreme violence. Beebe, reading Jung’s Red Book, interprets the figure of the murdered hero as the inferior function sacrificed by collective incapacity. Von Franz and Kerényi locate ritual murder at the origin of initiatory mysteries, linking it to death-and-renewal cycles. The term thus spans legal prescription, purification theology, tragic psychology, archetypal initiation, and the phenomenology of radical evil.
