I think trying to shoehorn the behavior of real people into convenient categories is uncertain enough with unlimited access to that person. When the only access you have is how they chose to portray a fantasy character in a video game, it's unthinkable.
Practically speaking, it's also irrelevant. Maybe it will make some players feel better if they think those they are blaming are somehow defective, inferior, or unable to help themselves, but it's not going to change what's happening in game.
You can conclude they are complete Richards though.
