If you believe in free will, I'd be very interested to know your beliefs as to whence it derives. If the universe is bound by a set of consistent physical laws governing the behaviour of all energy/matter, then every interaction is predetermined by the combination of those laws and whatever the initial state was. Free will therefore requires a supernatural component that is not subject to those laws and processes. Even at a more macro level, every decision you make is necessarily based on a combination of genetics and the contents of your memory, i.e. the sum of your experiences, and the interaction between those elements.
What we like to call free will is just the deterministic result of processes to complex to be understood, modelled or predicted.
