I guess most of you will say: No. If he had known it he would not have killed him. But if Satan did not know it then why did Jesus call Peter Satan when he told him not to be crucified? This makes no sense. And after all Jesus said so often that he has to be tortured and die and so on, was there no demon around who heard it and who understood what this means? I thought that Satan and the demons are smarter than humans, why didn't they get it?
