Ie on that day your son goes on a killing spree, and kills fifty people.
so in answer, of course it does, because you know you cant change it, (which negates your free will) and your son cant change if you told him, because it's pre ordained(which negates his free will).
No it doesn't I have the free will to return back in time and tell my son do not kill i still have free will. But not the power to control his free will, He still has the free will to disregard my advice and go on a killing spree. Just because i know he is going to go on a killing spree does not mean i have forced his decision either way.
know you cant change it, (which negates your free will)
It seems you are getting power of control over another and free will mixed up? Just because i have no control over my sons final decision does not mean i have no free will.
