Your whole concept of free will is illusory. There are no decisions which can be made outside the bubble of your experiences. All the things you see, everything that happens to you shapes your response. Your responses shape your environment. This cycle continues forever, and if a being could comprehend all the countless tiny elements at play, that being could predict the future. You choose what you were always going to choose. You are incapable of being random or acting outside of the influence of the universe. To assume anything otherwise is to liken yourself to a god.
