"I know somethings, therefore I am God" every medical doctor in history. There's a certain kind of narcissist that ends up in that field and pursuing that line of work. If you think it's "to help people" of anyone older than 5, you're kidding yourself. Granted there are degrees of narcissism and surgeons are without question the most...however even the "lesser" medical doctors (dentists for example) believe themselves to be of the highest moral and ethical stature. I've yet to come across a doctor worth very much, outside of ego self inflation and obnoxiousness.
