I would not be PE, at least I hope I would not be. I would be a manipulative chess master who uses chaos, seduction, and other means to manipulate and control the world to my heart's desire. But I'd never let anyone know who's pulling the strings, and would only resort to outright trying to take the world unless I had no other option.
I think my goal would be to become the real world instigator of morality and fate. Get the whole world to follow my own moral code. But I'd prefer to make powerful people my puppets or pawns and rule through them. If that doesn't work and I'd have to rule openly, and outright take over the world, I'd be like Sauron and enslave the minds of nation leaders or overthrow them and replace them with a individual who's mind is enslaved to me.
But lucky for you all, I'm a poor strategist and am not very charismatic.
What about you?
