Can we agree, that there's no one 'best interest for the people'? That there's a multitude of different opinions and interests that may be good to some and bad for others, that can be 'good' and still mutually exclusive?

I assume the benevolent dictator would be someone, who allows different opinion, and who allows his policy to be changed by his people. And if they want to be governed by someone else, he would step down, have his own power limited or stripped. That wouldn't be a dictator then.

And you'd still have to deal with his administration which has it's own momentum. The 'benevolent dictator' could simply be replaced (killed) by his own clique with someone more in line with their interests.
