The thing I always liked about Venom/Spidey was the idea that one regular guy who happens to me nice by disposition, chose the way of the hero. The other, bitter, chose the way (more often) of the villain.
It's the classic "If you could get infront of the guy always doing things better, would you?" debate. He chose to.
Introduce power and see the paths they take. Not original, granted.
