Kingdom Hearts Thread [Forewarned: Spoilers]

[wiimanclassic]

So I have a question, during most of KH2, before he fuses back with Roxas anyway, was Sora some strange mutant form of heartless that retained its mind and didn't have any of the crazyness seen in other heartless, or would all heartless like things(Sora, Ansem Seeker of Darkness) just kinda keep doing what they did before becoming heartless?

The question is Sora being some weird heartless unique or would all human shaped heartless act like they did in life?
