***does anyone think that Gollum might not be really evil?***

[Beruthiel]

So in short, it is all the ring's fault

I agree. Gollum isn't totally evil but he's just corrupted by the ring. In the Two Towers I read something about how he looked like a tired, old hobbit sometimes. This shows there was something other than evil in him and he was just normal deep down somewhere.
I wonder what gollum/smeagol would be like if he hadn't found the ring??
