Classicly speaking (judeo-christian speak) - not every decision IS free will, but COULD BE free will.
For example - the New Testament hint that Eve's decision to eat the forbidden fruit was the result of trickery (thus NOT free will), but the suggestion that it COULD have been free will (like Adam's choice) if she had not been fooled.
On the other hand, it brings up the thorny question: Did Eve use FREE WILL in allowing herself to BE fooled? Or was she genuinely fooled without reflective thought - was she even capable of reflective thought on the subject? Or was she just too dumb to figure out the temptation?
So then, can you be TOO DUMB to have free will? Is a severely retarded person capable of free will?
Thinking along these lines is causing me to seriously question the entire religious concept of "free will". I am starting to think (like Einstein did) that it is really just a logical excuse made by religious tradition for God's decision to punish the humans for something they were pretty much destined (and tempted) to do anyway.
