Well personally I'm pretty cynical, I also don't expect much benevolence from a dictator. There are examples of it in history though.

While I don't want to live under a dictatorship, I'd argue that a dictator will only be as good as the system that put them into power. A huge issue we have today in the US is that our political system is so broken and corrupt that the only people willing to work their way to the top are ones we likely wouldn't want to have power. It may be a democracy of sorts, but if the system is broken the leadership will match regardless of how many/few are in charge.
