Our choices don't matter becuase they are determinative. They matter because they are indicative. Addiction to porn is a devestating indictment of lust.
True dat. But the question you raised was "does God play dice". He either risked my succuming to lust when He created me as a free moral agent or I'm not free.
On a cosmic scale, when lucifer rebelled did he become a real enemy or a marionette - or was he just a marionette that appears to have rebelled? In humanity did God create a race of beings who can resist His will or does it just look that way?
There aren't any dice involved, God is God, he can handle the action.
