In addition to wanting the Sith to return, TFN wants the Jedi to think that the Sith are extinct again and they want the Sith to rule the galaxy again and they want the Sith to self-destruct again.

But that's exactly what happened in the prequel films!

History will repeat itself. The Enterprise will keep exploding, Bill Murray will never escape Groundhog Day, and Arthur will never get the Holy Grail!

You'd think a knowledge of the past would be valuable, like Obi-Wan wouldn't take Luke aside and go "Look, you must always assume they're out there so as not to let your guard down! That's what happened to us, and look where we are now!"

I'm really starting to see your point of view now. I can get behind no resurrection of the sith.
