All thoughts of revenge are born of the pain of helplessness. ‘I suffer’ becomes ‘You will suffer’. And let us not lie: Vengeance is invigorating. It focuses and enlivens us, and it quashes grief because it turns the emotion outward. In grief we go to pieces. In revenge we come together as a single pointed weapon aimed at a target. However destructive in the long run, it serves a useful purpose for a time.
