If the "omnipotent/omniscient Being" knew ahead of time what choices the created beings would make and what the consequences of those choices would be, then the "omnipotent/omniscient Being" also chose those consequences and is responsible for them.You can say freewill is an illusion, but that does not mean you are correct. There is no reason that an omnipotent/omniscient Being could not and does not allow created beings to make real choices.
