GamesRadar: "One in five Americans are born with some sort of personality disorder – something that makes them zag when everyone else zigs. It might be as subtle as a nervous tic, as confusing as Asperger's or as overt as psychopathy.
But mentally unstable individuals are a part of the real world – and part of the world of videogames as well. Sometimes their damage leads them to be horrible, monstrous villains, and other times it can make them loyal friends, or complex protagonists. No matter what it does to them, though, it's usually hard not to be sympathetic to their problems, and to, in a way, fall in love with them... even if they're murdering sociopaths."
