Free Will

Today I am thinking about the notion of free will; the idea that our actions are spurred by the work of our brain, our intention, and nothing else.  This is fair enough, but breaking down the very term "free will" seems to open up a contradiction in an of itself.  If an action is in fact, free, it is undetermined, unprompted, goes unpunished and unappreciated. If it is willed, it is determined, prompted and upon its manifestation, will serve as its own reward. And if we do have this “free will” at our disposal, what does that really mean? Does it function with destiny? If we are interconnected souls then are our personal or collective wills not predetermined by something like destiny? Fate? What about the (for lack of a better term) scientific end.  If we are evolved from cell formations (or whatever it is) and if it is will, what makes it ours? If we depend on this notion of science then surely it must be science that dictates our decisions; our free will. How does that fit in with something like crying?  Is that our own? Sometimes we cannot hold back tears, laughter; we make decisions we regret; what do these mean for free will? When the decision was made was it determined? Is the regret just another factor in the plan? Or is it random event one after the next. Science and emotion translating into a coexistent language, rolled together to create the illusion of free will?
