Dude i freakin loved Lupin he was so awesome i almost cried when he died. He had always been harry's favorite teacher, besides maybe hagrid or McGonagull(wrong i know), and of course dumbledore. He taught harry what i would consider to be harry's favorite spell, the patronus charm. It had gotten him out of many dangerous situations and in many cases earned him respect, such as as he was taking his D.A.T.D.A. owl, or when amelia bones asked him if he could do a full patronus. It reminded him of his father, it took his fathers form of a stag, and it had always been really special to him. Not to metion that the patronus causes happiness and joy and comfort to those who can cast it.

I always loved lupin though because he always tried to live his life despite of what he was, despite what people said about him. He was just afraid of making his family into outcasts, i dont believe he ever really felt sorry for himself, just sorry for what his presence was doing to those around him. and he died to protect harry, his friend just like he and sirius told wormtail they would do for a friend. He was a great wizard and a great man.
