DarkRose, I don't think he was a 'part of Sauron', even if we was totally corrupted - because he seems to have his own ambitions. In his conversation he says that Orthanc must be given to a leuitenant of Sauron's "more worthy of trust" than Saruman, and then looking into his eyes they realise that he is to be that leuitenant and become a tyrant himself. It sounds to me as if he had a lustful look or a proud gleam in his eye when he said this, and this is how they knew. So he seems to desire to become powerful himself. If he was actually a part of Sauron he would not feel any pleasure at this thought, but he does, since he is an individual.
