The Fellowship's True Purpose?

[Boromir88]

Boromir88, if we were to follow this line of reasoning to its conclusion, Smeagol should not have been corrupted either, and yet he was--almost instantly.

An explanation to that would be, Gollum was corrupted from the start. The Ring attacked Gollum's weakness, and made Gollum kill to get it. Where Bilbo, Bilbo was a lot kinder of heart, which is why he doesn't kill Gollum over it. Although, we do see a bit of the "nasty" Bilbo side, but still, doesn't kill in order to keep, or gain the ring.
