Hitchy quotes George Orwell's commentary on revenge, following WWII.
Properly speaking, there is no such thing as revenge. Revenge is an act which you want to commit when you are powerless and because you are powerless: as soon as the sense of impotence is removed, the desire evaporates also.
Who would not have jumped for joy, in 1940, at the thought of seeing S.S. officers kicked and humiliated? But when the thing becomes possible, it is merely pathetic and disgusting. It is said that when Mussolini's corpse was exhibited in public, an old woman drew a revolver and fired five shots into it, exclaiming, "Those are for my five sons!" It is the kind of story that the newspapers make up, but it might be true. I wonder how much satisfaction she got out of those five shots, which, doubtless, she had dreamed years earlier of firing. The condition of her being able to get near enough to Mussolini to shoot at him was that he should be a corpse.
