A narcissist would tend to display the sadistic aspect of his personality in one of two cases: That the very acts of sadism generate Narcissistic Supply to be consumed by the narcissist ("I inflict pain, therefore I am superior and omnipotent"), or That the victims of his sadism are still his only or major Sources of Narcissistic Supply but are perceived by him to be intentionally frustrating and withholding. Sadistic acts are his way of punishing them for not being docile, obedient, admiring and adoring as he expects them to be in view of his uniqueness, cosmic significance, and special entitlement.
