Sméagol: Hero of the Third Age

Nilpaurion Felagund, I don't think your theory is plausible. Gollum suppressed the good that is in him, to the point that, by the time he met Frodo, it was almost non-existent. He collaborated with the evil side of Sméagol, the one that killed Déagol in the first place, allowing both personalities to be corrupted by their lust for the Ring, which had the same effect on them as it had on Morgoth and Sauron--it dried up their potential for life, for the chance to awaken from their bondage.

Maybe the good side of Sméagol was briefly awakened during his encounter with Frodo, but it was in such a bad shape it never had a chance to really stand out--except probably during Cirith Ungol. Even then, it was so volatile, that only a sharp word from Master Samwise was needed to bring it into exile forever.
