But maybe there was another small jedi purge caused by one sith who has learned from an ancient holocron and this time it is not like what we saw in Episode III and I can possibly see a resurrected empire so if the darkness theme is not pointed directly at the jedi it should be about the rise of an even worse empire.

That sounds really dumb and clichéd, no offense. That's what the EU has done way too many times already and exactly what shouldn't happen in the movie.
