If the Force has no will of any sort, then it's kinda useless as a story element. It's gotta want something, or represent something that the characters should want.
If the Force is maneuvering characters like a puppetmaster, then it's wrecking the story.
That's why the best solution is that the Force has a will, but it's not something either the Jedi or the Sith are willing to accept: that to win, they must lose. Both sides are so locked into their conflict mindset that they can't comprehend the Force at all.
That's why Luke is an interesting character. He seems to be the most likely to finally comprehend the true meaning of the Force at long last: victory through surrender.
Forgiving Anakin was a good example of that - after all of his crimes, it's not "right" or "just" that he be forgiven, unless you've accepted that you must abandon the conflict-oriented mindset, even if it means abandoning the search for "rightness" and "justice."
That's not something that's easy for anyone with a self-image as a "good guy" to accept, but if the answer were easy and obvious, the Jedi would have found it without spending eons flailing around, fighting the Sith and getting nowhere, since the Sith keep coming back - shouldn't that alone be a sign they're doing something wrong?!?
Anakin falling to the Dark Side was a message from the Force, you idiots!

Ah what fools these mortals be...
