Well, since none of the local dictators enforced civil rights and liberties as you would understand it, I'd say they are better off with democracy. The fact that they're taking a route you don't personally agree with doesn't automatically deligitimize what they're doing. The benevolent dictator is nothing more than a Platonian ideal. A return to the western backed dictatorship is only going to ferment the contempt and anger that the Middle East has for the west, and cement the idea that American ideas are inherantly a double standard. Freedom and equality for the west, iron fisted security for the middle east.
Remember, at the end of the day, even the Muslim Brotherhood isn't all that interested in establishing a totalitarian theocracy despite what the Western media sometimes frets it does. Yeah, they're a religious party. But on the whole they aren't any more dramatically religious than some members of the US government. If you really do want to change the fact that these things occur, you need to be capable of entering into an equal dialog with the local populace. Assuming that American values are the universal best values and then talking down to people that view things otherwise is only going to make the situation worse. Accept that while there are aspects of their society that need to change, demanding that they change without addressing the issues that the US has is nothing more than cultural arrogance.
