A complex Gollum

[Birdland]

The ring is/was far more powerful than many could have guessed, and he was a simple being...I do not believe he could help but to strangle Deogol!

I don't know about that. Frodo lived in Bilbo's house for years, knowing the Ring was there, and never once thought of strangling Bilbo. (Well, maybe once or twice when he started singing that "Road" song for the umpteenth time.)

I'm still of the opinion that Smeagol was a bit of a wanker all along, and the Ring just brought that out ten-fold.
