How did gollum transform from the human he once was to the "thing" he is today? In Lord of the rings they show him finding the ring then killing his friend when he tried to see it, maybe the ring made him that way...........but then it also made him immortal because he is like 500 years old. (you would have to see the Lord of the Rings to know how old he is) I'm probally reading too much into this, it is fantasy after all.
