No, I don’t think I could.

The problem with dictators is that you put every action under the context of a single person’s perspective. Even if you go in with the best and most altruistic intention, no single person is able to tackle every issue from every angle, and you will inevitably end up committing an injustice by a simple lack of awareness.

Not to mention that many issues are of relative morality to different groups, so to one group you can be a savior but to another you will always be a despot. Whichever interpretation ends up as the definitive one depends on how willing the offended parties are to overthrow you.

A democratic system is not perfect and (depending on perspective) may not be as effectual at bringing out positive change as an altruistic dictator, but the concept of distributed responsibility/distributed blame reduces the likelihood of a coup/revolution (emphasis on reduces, not eliminates) as long as the political apparatus is seen to incorporate or acknowledge everyone’s perspectives in the decision making process.
