...A god, a hero, an over lord... Sure you could end up being seen as a spy or whatnot but you could advance the human race so days such as present in the past would seem primitive so in the future... You could be even more amazing ;D You could prevent wicked marks in our history from happening all sorts you could do, I personally would place myself as some kind of grand arch mage wizord! Inventor of Aspirin, The wheel, fire, sandwhiches, sugar, coffee, weed, flight and able to forsee future events! mowhwhwhaha. I think for me I'd be like that fat kid from the new film "Megamind" Titan, he was created with the best intentions from the pure essence of good, to be a hero and protect, shield and defend good and the people... But the power was just too much... lol And knowledge being power you send even the most average of person back they would have knowledge long time. Had a dream like this recently... I went into the Sharpe TV series... (Napoleonic era) I lead a crack assassin/sniper unit of 17 drones we were all equipped with modern rifles and obviously could hand Napoleons Soldiers their asses. Would venture out in our ghillie suits and eliminate entire battalions and regiments on our own lol... Sometimes pure silence ( .338 rifles) or in a rain of fire!! If we got located (MG42's! )Became feared by all the French and heroes to all the British Anyways it was a cool dream.
