The Quest For Answers

[Mouth of the Dark Lord]

Hey,

I'm new to Entmoot, so I'm not sure if such a thing exists here yet, as I didn't bother looking. I decide I wanted a thread to answer all those questions that are unanswered, and I myself have one. I think myself to be a LoTR Fanatic in general, but I know there are those that Live and Breath LoTR, I want them here to answer peoples' questions...
As I said I'll ask the first. When the ring was destroyed what went with it, I at first understood that all evil was drained from Middle-Earth, but now that I've rethought it... It seems less sensible, compared to my new view that only the evil united under Sauron's power was taken, as he was the puppeteer and the puppets can't go on without their master... This just made more sense to me, but am I right?
