Dean Winchester is the older brother of Sam. This guy loves classic rock and heavy metal.
He has more of a sense of humor than his brother, as Dean will joke around about some of his and Sam's adventures. He's not afraid to make sexual cracks and innuendos.
Mostly, Dean values his family and their safety. He has killed a demon and its human host in order to save Sam's life, and he's sold his own soul to save Sam's life.
