The author explores revenge as a complex response to injury that blends affect, fantasy, and action, drawing on psychoanalytic theory alongside literary treatments of vengefulness. Revenge is framed on a spectrum from more bounded, reality-tethered efforts at redress to chronic vindictiveness shaped by narcissistic injury, envy, and defensive refusal of loss. Brief clinical vignettes from individual, couple, and group work illustrate how revenge may preserve attachment to the offending object, destabilize self–other boundaries, and intensify countertransference pressures, while raising technical questions about interpretation, survival of attack, and the timely use of limits. The paper was first presented in December 2024 to the Center for Modern Analysis in St. Petersburg, Russia.
