My own personal interpretation of Ben Tennyson had he not become a superhero.
All Ben's ever wanted to do is get out of Bellwood. But I figure that when leaving Bellwood actually became a possibility for him he would have realized that he also wanted to do something important with his life. Something that could change the lives of others for the better. Thus, he would have join the United States army. Regardless of whether or not he'd have struggled with the training, Ben would've made it into the field only to realize that the world and the wars just aren't as black and white as everyone said they were going to be. And that that has a way of eating at you.
My purpose here is to depict the struggle that would've existed between Ben's open-minded, idealistic nature and the strict by-the-book lifestyle of the U.S. army.
