Free Will - just how far can it go?

So I have no choice on ending my soul?

I fail to see why I should live up to some amm Creators expectations...just because he/she/it created me.

And so if I reject my creator...than what? It will send me back to Earth to live another life?

If I have no free will I am getting this any way...so this creator has nothing to "threaten" me with... I can reject it at any time. Even now.
