Dean Winchester is the eldest brother of the Winchester boys of Supernatural, and he is a role model. Since the death of his mother through a supernatural occurrence, he has been following in the steps of his father, John Winchester. John had made it his life's work to destroy demons and other supernatural creatures after the death of his wife, and his son's Dean, and Sam traveled with him.
Dean drives a black 1967 Chevy Impala given to him by his father. He is the hunter. He relies mostly on guns and uses a Colt 1911. He has an armory of weaponry that he carries in the trunk of his car.
He likes hunting down those demons out there. Sammy, as he likes to call his brother, is the brains of the operation. He attends to all the research in their hunting.
Dean likes to dip his hand into many things. Among the things he enjoys doing is gambling. He is also a con artist. These are not the traits that make him a role model, but he does use these resources to help people who are in trouble.
The one other thing that Dean will readily admit is that he is a freak, but he is okay with that. He knows that he and his brother were not raised the same as other kids and he accepts that.
Dean is a loner, but he really does not like to be alone. When his father disappeared who had been travelling with him, he went to get his younger brother because he did not like hunting alone. He likes to know that someone is thinking about him and he is important. That is why he would readily give up his life for his brother.
