this has probably been mentioned .. but I'm too lazy to search 6 pages to see if that was the case..
first of all, just because, or even if, the Force has a will doesn't mean it's ultimately evil or good .. it can be both or neither!
That argument is false .. since God may just as well not care, or ultimately let the decision belong to the human in question! if you choose to be evil you must face the consequence .. he still punishes you at the end, hence he is not without power to control you! you can't escape your ultimate destiny in Christianity .. it's either Heaven or Hell at the hand of God..
unless you view it like, since God is all knowing everything must be predetermined .. hence there is no free will!
but since every decision can have a multiple outcomes, you can also just say that God can see every outcome, and let's the ultimate decision be up to you .. hence you have a free will and God is still omniscient..
I believe that the Force in SW is intented like the guiding hand .. the one that grants you the power to change your world .. and has a destiny for you that you can approach in different ways! so it's like a predetermined destination, that you can travel to by which ever road you like!
