Throw Quantum mechanics into it then we have free will but so what? Whether I am on a predictable path and feel I have free will or if quantum mechanics would make a different outcome allowed if the universe was replayed.Quantum mechanics doesn't introduce free will into the system. It introduces uncertainty.
The distinction between a truly deterministic system and a chaotic one isn't actually meaningful. In the latter case, we can't predict everything because of inherent randomness, while in the former, we can't predict everything because we're limited in the amount of knowledge we can obtain about the system, much less process.
What we can do is make predictions that are less than 100% certain by assessing probabilities. The more macroscopic the scale, the more likely these predictions will hold. For example, if I try to predict the exact position of an electron, I'm highly likely to be mistaken. On the other hand, if I predict that a ball will fall towards the ground when I drop it, my correctness is virtually assured. Even in the second case, though, it is conceivable that enough virtual particles could appear above the earth to create a strong enough gravitational pull to cause the ball (and everything else on the planet, plus the planet itself) to fall towards it. It's also staggeringly unlikely, since it relies on the synchronicity of an effectively uncountable number of unlikely events.
The easiest thing, and most practical one in my opinion, is to acknowledge that while free will doesn't exist, we can behave as though it does.
