Well, I think you're being overly generous with Singapore's human rights record, but even ignoring that, what happens when the dictator dies or hands power to his sons or whatever? You have no mechanism for a sane transfer of power nor do you get to vet the candidates. Also, what if he's merely 60% benevolent, how do you fix the other 40%? For example, corporal punishment continues to exist in Singapore. Why would a benevolent leader allow that? Worse, what avenues do you have to change this? You don't have any in dictatorship. Heck, Singapore has the world's highest execution rate relative to its population. It also executes drug dealers. Again, how can you change that in a dictatorship? Who gets to decide what is "benevolent" here?
