[Rune Son of Bjarne]

Well, actually Gollum kept the ring in his possession for around 500 years. . . Frodo was not cured by the effects the ring had on him on a few years, so you can hardly expect it to happen to Gollum.

The difference between Bilbo and Gollum is that Gollum is so corrupted by the ring, that it pretty much controls his every move. (At least the motivation for all his actions is to re-gain the ring). He no longer has any willpower to withstand the ring and its real master.

Master is not the right word. . . Sauron was the Ring! Therefore when Gollum was consumed by the ring, he was consumed by Sauron and had to obey. Bilbo didn't have the ring for that long time, although it was beginning to have a certain power over him, it was not devastating like in Gollums case.


and yes Gollum and Bilbo did have more or less the same origins.
