Most likely the First Group of Imperial Knights were trained by Empress Jaina Fel
I'm listening.
I will disagree with you here, Kenobi never says anything about there not being any darkness,
Not directly, but he is making reference to the Jedi belief that the Chosen One was supposed to destroy the Sith, and bring balance to the Force. The Sith represent the bulk of the Dark Side in the galaxy. Destroying them would only further UNbalance the Force. I know I've referenced the theory that due to this imbalance of light to dark for so long is what allowed the Sith to decimate the Jedi. With their drastically reduced numbers, the Force was closer to being balanced than it had been since the battle of Ruusan 1000 years prior.
just that the Force as a whole cannot be wholly dark. What Sidious wanted done was all Jedi and lightside Force users to be destroyed, effectively shutting off all light in the galaxy. There would be no balance, and it would be left in darkness.
True. The more I think about it the more I draw the conclusion that despite playing the long con, Sidious was exceptionally short sighted. HE abandon the Grand Plan in favor of merely wiping out his opposition and never trained a true apprentice. He wanted to live and rule forever.
BUT, {I can't believe I'm referencing this crap} in TFA the darkness had risen once again to a superior position and the Force reacted with a balance. <barf>
He nearly did this, which is why the time between ROTS and ANH is called "the dark times" ("Before the Dark Times, before the Empire" - Old Ben). Had Anakin succeeded (and Sidious, because he failed to kill Yoda too), the galaxy would have been left in darkness. Instead, Obi-Wan, Yoda, Cal Kestis, Caleb Dume, Jocasta Nu and a few others survived (for a time) allowing the galaxy to be left with essentially a nightlight.
FTFY
But with that, the Force is still imbalanced because there are still more Jedi operating than Sith. I know there are also lesser Dark Side users in the galaxy, Night Sisters namely. (And screw Feloni's bad story telling)
Also, it is necessary to note that darkness is the absence of light. Therefore, if all darkness (Hutts, Cartels, Underworlds, Bounty Hunters, Mercenaries, etc.) could be removed, there could theoretically be "absolute" balance. Unfortunately that is completely impossible.
By this logic, all it would take to counter the Dark Side is good people to stand up for what is right, regardless of sensitivity, in order to balance the Force. In which case, the Force would, for the most part, never be terribly unbalanced. Kinda lends to a limp story.
I wouldn't say the Jedi are hypocrites, more of they just do not have a correct understanding of what balance looks like. Or else they are just looking for that "absolute balance" I mentioned earlier, which as I said, cannot exist.
Even with "absolute balance" they would still act against forces that seek to spread fear, destruction, and death. Hondo's lot weren't exactly the Salvation Army, so despite the lines separating allies and enemies getting real fuzzy during war times, in times of peace the Jedi would have completely shut down that pirate organization.
The Je'daii understood absolute balance.
