You are not wrong to feel as you do. Feelings are feelings.
But I'm not sorry to see Saddam leave this life the way he did. As I see it, he earned it - building palaces while his own people starved to death, lived in grinding poverty, lived in fear of torture or beatings or "disappearance" at the wrong word said in front of the wrong people. Letting your children, particularly your sons, run wild and live like gangsters, an opulent lifestyle financed with the blood of innocents. Even if he never personally touched them, the taint of all that blood was ultimately on his hands.
Of course, I've lived a life that was informed, though not directly affected, by a totalitarian dictatorship (without it, I'd never have grown up in the U.S.) so my feelings may be a little more highly colored than others' on the subject.
I, for one, am not sad to see him get his just desserts. It just saddens me to think that we have to share a world with others like him, most of whom outrun the justice they deserve to have served on them.
