Revenge served clammy
It is not necessary to have any sympathy for Saddam Hussein -- who was a revolting thug -- to see the futility of his rushed and widely publicized execution. Alive, the only people to whom he presented a danger were those who might be mentioned in the evidence he could give in trials that will now not be conducted. Dead, he is a monument to his failed trial and the fictional government that has now taken its useless revenge on him. Some people will now try to turn him in a martyr, which can only further increase the level of violence in the world. As far as deterrent effect, his killing ought to prevent the survival of the sort of political movement he developed about as much as the hanging of Mussolini did.
