 Religion, and even more so, “good acts” can only be attributable to free will. Or to put it another way, morality is contingent on free will. If God were to put special powers into comets such that they could influence human actions, then comets—these material objects—would be superior to humans. Humans would be the playthings of comets, and “good acts” qua determined acts would no longer be good. On the other hand, human acts would be subject, to what in the Middle Ages was deemed as “Fortuna”, predestination, and to some extent providence.
