Are you saying that Frodo had a destiny from which he could not deviate, but Sam essentially had no destiny? That Frodo was bound by his destiny to be the Ringbearer, but it was not Sam's intractable destiny to accompany Frodo? Why would this idea of predestination only affect Frodo's free will and not Sam's?
