[Theoric Windcaller]

Yes, I did trust Smeagol, but I knew that Gollum was and always would be evil. I knew that eventually Gollum would overcome Smeagol and persuade him against the two Hobbits. It's a common fact that Gollum has always wanted the ring, and he would've done everything in his power to get it. Gollum was going to get into Smeagol's head one way or another, and he was going to get to the ring if he had to go through hell and back. And he did, he went through Mordor only to claim the ring, but fall to his fiery death once his prize was claimed.
