I think that is a bit of a stretch.All powerful superhero is feared by the public and is yet a bit detached from the public as well. And his very existence plays into world politics.
Both Dr. Manhattan and Superman fit this mythos.
Are you dismissing this as a coincidence?
Manhattan is detached from humanity his and the people he exists beside because he has advanced so far past human beings that they were like ants to him.
Superman is detached from the public as you state because his human father ingrained in him a distrust of people/the government based on fear of how they would treat him.
One character lost his humanity while the other is incredibly human.
