Depressed Soul, yes a few individuals in the Bible were predestined but though Christ's betrayal was prophesied that does not mean that when Judas was conceived in the womb his path was sealed.
So invisible guy in the sky DOESN'T know everything? He is NOT omniscient, as Christians and the bible claim? That means it is NOT the god you claim to worship.
He may have been chosen for his bad tendency but a whole host of other men at the time could have filled the bill.
So god picks, specifically, who he will kill and what sin they will commit even before they have done wrong? So it was predestined before he made the choice, contrary to your prior claim.
