We are all certain that within our frame of existence we don't understand all the possibilities in our lives. That itself has proof that we do not have a hundred percent free will. If we chose to do whatever we want we would always be right and if we chose to do what we wanted to do we would always be free. This reality offers neither of those possibilities; we're neither always right nor always free. Reality being set in stone and only allowing so many possibilities to exist is as free as our wills can achieve. There are predefined boundaries in what we able to possiblly complete. This subject brings me to crime statistics; how many criminals intended to commit the crimes they did knowing they would be imprisoned for years? Notwithstanding other Universal events such as probability, inability to change your environment, or psychological / behavioral norms, all of which are not free choices. What I'm saying is all free choices are still drawn towards one Ultimate.
However self-serving it sounds, if all of our choices are drawn to one ultimate, that would be our fate.
