Re-reading the Lord of the Rings, Chapter 42

Tolkien uses this chapter to introduce a more primitive form of evil, a more beastly one, and that in turn he uses to clarify Gollum's position, as not only having joined the life of beasts, but also their kind of scattered cunning, based on specific points of departure, between which it is lost.

It is interesting in the light of this to look at Gollum's ideas of what he'll do, once he's wielding The Ring again, for he used it previously for little, and it doesn't appear likely that he'll be able to use for more, only because he now knows that it's Sauron's and that Sauron wants to have it back to rule Middle-earth with it.

It's like Gollum's human evilness tries to rise in vain over his beastly evilness, for in the end Gollum can't think of more than a full stomach either.
