Why God doesn't stop satan?

[R00tKiT]

P1 is not a sufficient condition for free will unless you include the proviso that choosing in P1 refers to freely choosing.  However if it does, it begs the question and the argument is invalid.  So P1 cannot be a sufficient condition for free will without begging the question.  Free will implies that both P1 and not-P1 could be true.  However P3 rules out the possibility of not-P1, so P3 rules out free will.

P1 obviously entails free will. There is no begging involved, I am not trying to prove free will based on P1, I already assumed D has free will by asserting P1.

And of course P1 is not a necessary condition of free will, let's not play this silly game, I am giving one example of free will (choosing some flavor of ice cream), obviously one can have free will and never eat ice cream in their life.

You say "P3 rules out free will", which is a claim you didn't prove. P3 is exactly equivalent to P2 as I proved before. omniscience mean knowledge of all true propostions. If P3 is true, then P1 is true at all times, and a fortiori, ten years ago, therefore P2. Inversely if P2 is true, then because God is omniscient, God knows about P1, therefore P3.

I don't feel the need to repeat a simple explanation for how free will and foreknowledge are, by definition, mutually exclusive.  

If you believe in the author of creation, and you've said that you do - you believe in fate.  You may have negative ideations about "fatalists" - as your shaman tells you they are, but by expressing such a position you have identified yourself as a fatalist no matter how much you think fatalist heretics deserve the sword.  

Know thyself.

In truth, whether we have free will or there is some author or knower of creation is unimportant to me.  Neither state of affairs has anything to say about why I don't bend the knee to your trashgod.

If we don't have free will...I just can't worship trashgod, because I'm not enough of a garbage person to do so.
If we do have free will, and even if I were a garbage person, I still have the constitutional volition to say no to at least one bad thing.

Worshipping a deity is an entirely separate issue. But if a deity exists and instructs us to worship it, we can safely assume it's also a moral authority, which means worship is a good moral imperative by definition.
