The fun thing is you can never know if there is fate, because perhaps it is our fate to never know it. Same thing with proving that a god exists or not. If there is a God he could make you think there is no God, why would he do that? Well if there is a God there is a chance that our sense of logic is fake.
Same goes here: It might be our fate to not know it.
Also, unless there are parallel universes you can only make one choice every time, as such there is only one path for you however you still choose this path yourself.
