In some ways I think he is great in becoming someone much different than he would have been had he not had the dreams and desires to grow and be successful. However, like a tragic hero, he has a flaw that keeps him from greatness or true success. His ill-conceived love controls him and obsesses him.

He loses himself, and this is truly tragic.</span>
