The obvious objections to the execution of Saddam Hussein are valid and well aired. His death will provoke violent strife between Sunni and Shia Muslims, and between Iraqis in general and the American occupation forces. This was an opportunity to set the world a good example of civilized behaviour in dealing with a barbarically uncivilized man. In any case, revenge is an ignoble motive. The usual arguments against the death penalty in general apply. If Bush and Blair are eventually put on trial for war crimes, I shall not be among those pressing for them to be hanged. But I want to add another and less obvious reason why we should not have executed Saddam Hussein. His mind would have been a unique resource for historical, political and psychological research: a resource that is now forever unavailable to scholars.
Imagine, in fancy, that some science fiction equivalent of Simon Wiesenthal built a time machine, travelled back to 1945 and returned to the present with a manacled Adolf Hitler. What should we do with him? Execute him? No, a thousand times no. Historians squabbling over exactly what happened in the Third Reich and the Second World War would never forgive us for destroying the central witness to all the inside stories, and one of the pivotal influences on twentieth century history. Psychologists, struggling to understand how an individual human being could be so evil and so devastatingly effective at persuading others to join him, would give their eye teeth for such a rich research subject. Kill Hitler? You would have to be mad to do so. Yet that is undoubtedly what we would have done if he hadn't killed himself in 1945. Saddam Hussein is not in the same league as Hitler but, nevertheless, in a small way his execution represents a wanton and vandalistic destruction of important research data.
