The problem of free will and determinism is a false dichotomy. A deterministic world does not preclude the possibility of free will. I define free will as the ability to analyze different courses of action and choose to take a certain course of action based on whatever values you care most about. And though that action may be determined, in that: given the present circumstances (atomic functions, chemical processes, etc) of the world only one course of action may occur, it does not mean that you are incapable of analyzing different paths. You don't know what's going to happen next, despite the world being deterministic.
So this brings us to another definition of free will. Perhaps free will is not the ability to change a deterministic universe, but the ability to conceive of different possibilities given a certain situation and "choose", based on whatever values one holds, a course of action.
For example: I'm at a vending machine deciding between Coke or Sprite. I am determined, given the chemical processes in my brain, to choose Coke. However, I am able to conceive of the possibility of choosing Sprite. I am able to conceive of the consequences of choosing Sprite, instead of Coke. I am able to weigh the costs and benefits of choosing one over the other. And, most importantly, I do not know, initially, what is determined by the world. However, given whatever values I hold more dearly, I ultimately "choose" Coke.
So, then what is "unfreedom", in my philosophy? I suppose the inability to even conceive of any possibilities, except the one determined. Or perhaps, it'd be doing something you really don't want to do. For example, smoking crack, when you're addicted to crack, not because you really want to smoke crack. You can want to stop smoking crack, you want to do something else, but the physical addiction just overwhelms the brain, preventing any sort of circumstantial analyzation.

If you believed in free will you can go up to any random person in the street and stab them. Then you could step away and say, "nope not guilty, it was free will". You would have no reason to stab the man, you just did because you could. Free will suggest you are in control of your actions but you are NOT guided by reasoning and the concept of choice which i will explain shortly.
I think you're wrong. You're saying that free will is essentially pure randomness. If your actions are guided by absolutely nothing, then it's pure luck whether the coin flip in your head comes up "Stab" or "Don't stab". Randomness isn't free will. A random universe is the exact opposite of a determined universe. Without limitations of some sort, then the universe would be purely chaotic (ex: the laws of gravity may stop for no reason or change for no reason).
That's the true dichotomy: Determinism vs. Chaos, not Determinism vs. Free Will.
