Wounded pride has often been the simple catalyst to make a mild man into a revengeful killer. At other times it could be just the act of forgetfulness or a misplaced word, a joke about trousers or a suggestion that you take a walk in the traffic. If it is true now, it certainly was around in 18th century France. Who were King Louis XVI and Queen Marie Antoinette to know that at their coronation in 1774 that the 17 year old, frog-faced youth staring at them in sodden knee britches and holding a speech specially prepared for the occasion was to take his revenge nearly 20 years later? Maximilien Robespierre was that person. He never forgot the incident and made sure others around him remembered it too when France ejaculated into revolution in 1789.
