Serenity, if we were to follow that "free will" example, if I was a parent of a young child who wanted to take a large knife out of the kitchen and go next door and kill the kid who lives there, I would have to allow him to do it, because he had free will. That's basically what the "free will" argument is suggesting.
That's part of the fallacy with the "all-powerful, all-loving, all-good" deity that many keep conjuring up. If all that was true, what about evil, violence, hatred, and all the other horrors that mankind inflicts on each other? We would have no choices at all.
Gary, I remember that game. It was called Telephone.
