"a person with a psychopathic personality whose behavior is antisocial, often criminal, and who lacks a sense of moral responsibility or social conscience."
Thats what pops up when I looked it up lol, Actually that describes me in a lot of ways. But yea, I think Gary does what he does because he wants too. He has a lack of friends simply because he wants to. Or I could be wrong, and you may be right. Take into consideration though, he had Pete, and Jimmy, but we all seen how that turned out.
