Maybe i'm going to be a super geek for saying this, but has anyone read the old Avengers comic book Emperor Doom?
Dr. Doom finds out a way to mind control everyone in the world. All the nations of the world elect Dr. Doom as Emperor of the world, and he creates a paradise on earth.
Then Wonder Man (not woman) is able to find out how to overcome his mind control and puts together a team and they go and overthrow Doom, and make the world "right" again.
The last panel in the book has Captain America saying "we've either done the world its greatest service or the worst wrong in history, only time will tell"
I think i'd like to try and make the world in the image i think it should be, like Dr. Doom in that comic book.
