I believe in fate when it comes to situations such as love because that is something you don't totally have control over;however,things that you have control over and have to make choices about affect your future. in different ways depending on your decisions.
Heisenberg's electron uncertainty principle disagrees with you.
Only if you're radioactive.
What's, "free will," supposed to mean, anyways? If it means that it's literally impossible to determine what actions someone is going to do (Even with omnipotence and/or some kind of reality simulating supercomputer), then it sounds pretty scary--at any moment, someone could come to the conclusion that they want to kill you, seeing as how free will would imply that thoughts are not predetermined by past experience or the lifetime of conditioning meant to give people personality and prevent criminal acts. Luckily, this doesn't appear to be the case. If it's just minor things (What color socks you choose to wear, I don't know) then it probably doesn't even exist in the first place.
If it's, "Nobody knows what I'm going to think or do, even though it's possible," then it's mostly a matter of whether or not any omnipotent beings actually change things in this world. If they stay out of it, then it fulfills the requirements of free will as far as we're concerned. If it doesn't, then yeah, no free will.
