Free will is the assumption that who we are define the decisions we make. A criminal is a criminal because they chose to become so, they are the reason for the direction they have taken in life. A decision rests on the soul of the person who made it. Now we have learned that it isn't true. A criminal is a criminal because they were born with the genes that spur reckless behavior, they grew up in an environment that encouraged criminal action, not because "they" are criminal scum, but because the world they live in defined who they are. Free will is the idea that it's meaningful to be human, that what we do is something important, something special. At the end of our day, it's not the choices we make that matter, that define our path, it's who we were made to be by what is around us.
