Betrayal occupies a structurally central position in the depth-psychological corpus, functioning not as a pathological accident but as an initiatory necessity — the very mechanism by which primal trust is shattered and consciousness advanced. Hillman’s extended treatment in Senex & Puer remains the locus classicus: he traces a developmental arc from primal trust through betrayal to forgiveness, arguing that betrayal belongs constitutively to the father-son mystery, to fatherhood itself, and ultimately to anima-integration. Betrayal, on this reading, is not a moral failure but a revelation — the moment when the word proves weaker than life. Hollis reinforces and extends this by articulating the trust/betrayal dyad as a structural paradox: each term presupposes the other, and intimacy is impossible without the depth that makes genuine betrayal possible. Estés brings a feminist corrective, showing how betrayal cascades matrilineally and socially, shaping the expectation-structure of women who have been failed by their own female lines. Kalsched situates betrayal within the traumatic rupture of the self-care system, where the rage of the god-like protector mirrors the original wound. Nussbaum, from a philosophical-tragic perspective, reads the encounter with betrayal as the price of living on — of remaining in contact with worldly contingency. The field thus holds in productive tension the initiatory (Hillman), the relational-paradoxical (Hollis), the sociocultural (Estés), and the traumatic-archetypal (Kalsched) dimensions of the term.
