There is a consensus on this forum that Eywa controls all action on Pandora, but this raised an interesting question about free will. If Eywa controls/influences all action on Pandora via the bio-USB links, do the Na'vi have true free will, or are they simple obeying the orders that Eywa subconsciously inserts into their minds when they link with her to keep the balance of the world. This would change Eywa from a caring god to one of brutal conformity where any deviation is crushed by mind control.
And now we're getting to the crunch point, if this line of reasoning is correct, how do we know that Jake Sully defected from RDA completely of his own free will? When he linked with Eywa, she may have manipulated his mind to enhance his feelings of connection to the Na'vi and the rejection of RDA. Brainwashing if you will.
