The reason we see deranged or at least nasty and unpleasant dictators in the Arab world is that Arab societies are deranged, nasty and unpleasant–thanks largely to the brand of Islam practiced in those societies which is particularly deranged, nasty, and unpleasant.
In the Arab world you can have a brutal authoritarian who tries to restrain the even more brutal religious fanatics, or you can have religious fanatics who lash out at anyone who does not see the world as they do.
