Revenge, Rosenbaum argues, is not the problem. It is, in fact, a perfectly healthy emotion. Instead, the problem is the inadequacy of lawful outlets through which to express it. He mounts a case for legal systems to punish the guilty commensurate with their crimes as part of a societal moral duty to satisfy the needs of victims to feel avenged. Indeed, the legal system would better serve the public if it gave victims the sense that vengeance was being done on their behalf. Drawing on a wide range of support, from recent studies in behavioral psychology and neuroeconomics, to stories of vengeance and justice denied, to revenge practices from around the world, to the way in which revenge tales have permeated popular culture—including Hamlet, The Godfather, and Braveheart—Rosenbaum demonstrates that vengeance needs to be more openly and honestly discussed and lawfully practiced.

Aquinas does list a virtue whose name is translated as "vengeance."
I don't expect liberals and others with mushy-headed ideas about "love" to accept Rosenbaum's case.
