Another interesting aspect is: does your argument purporting that omniscience precludes free will also apply to god himself?
If you think people can't be blamed for their actions because they can't help but to do what god already knows what they'll do; and
God knows everything that he will do himself;
then you likewise have no basis to blame god for his actions.
