We all know Organization XIII is an opposing group to the heroes. But that dosen't exactly make them villians, esspecially since they desire to be complete. Anyway, Vexen willing went against Marluxia's orders shortly after Marluxia threatened him. Vexen was told sorry to "forget his memories and listen to his heart" as well as tell Sora the existance of Roxas. He was also trying to tel Sora what Marluxia was doing to him. So in other words.... Vexen was trying to SAVE Sora? O___O It seems like it, he didn't have anything to gain from it as far as I see it. If he was really trying to save Sora from Marluxia, why?
