Right outcome, wrong process
But the trial did reveal the horror of Saddam's regime. It revealed beyond any reasonable doubt that his rule was a reign of terror that we were right to bring to an end.
The unsoundness of the trial is, therefore, doubly regrettable, because it undermines the legitimacy of the sentence. Hopefully, he will live to see through the next trial - ideally, trial after trial after trial, for all his crimes - and fewer people will be able to deny the truth of his evil.
