Dictators care about how they are perceived because they used skills in manipulating how they are perceived to get into the position they are in. Making it a self selecting group. But when you change “how” they get there to simply be that they were given superpowers at birth, you remove the self selection. So now it is just a random sampling of the population, which in my opinion skews toward not caring as much about how they are percieved if they don’t need to.
