What exactly happens if the Jedi just leave the Force to the Sith?
I can think of plenty of political consequences - the Sith take political control of the galaxy, build an army, and have an empire of their own. In other words, the consequences have very little to do with Light/Dark balance of the force.
However, while that's happening, the Force is probably going to tilt more and more towards the dark. What I'm curious about is - what are the consequences of that?
Now, I am certainly imaginative enough to think of answers like "things start dying everywhere." But are there any canon examples/descriptions of Force imbalance consequences for which we can't directly blame some Sith and his/her hunger for power? Or is there at least any indication that the Jedi's obsession with balance is something more than dogma?
