God didn't 'explicitly direct' Satan.
Satan appeared before God and God offered up his servant Job as an example of a righteous man. Satan scoffed and claimed that Job was righteous only because God had blessed him with health, wealth and so on. Satan challenged God by stating that if God removed His protection from Job and allowed Satan to bring Job grief, Job would curse God. Satan contended that Job's faith and righteousness were based on his material comfort.
God then allowed Satan to smite Job but not to take his life. When Job lost all of his material possessions and did not curse (blame) God, Satan claimed - to God - that if Job was physically afflicted, he would abandon his faith in God. Job was and Job didn't. I think we all know the rest of the story of Job.
God is in control and knows what will happen. He knew before Satan ever came to Him that Job would not blame Him for his troubles but God did later condemn Job's complaints as well as Job's friends lack of faith.
Men are constantly presented with the choice of doing right or wrong. Most of us choose wrong, which is why we need a savior. God knows who will do what. Mr. Atta could have decided to abandon his mission of death on September 11th but God knew he would not. He allowed the mission to go forward, having another plan for the thousands of soon-to-be-dead occupants and rescuers. God has numbered the hairs on our head - He certainly knows when we will die and how we will die.
I do not believe that we are simply robots, pre-programmed by God. We can make choices and God has a plan for each of us. When we falter, He can pick us up and set us straight. We will follow His plan if we follow His will. Those outside of Christ do not know His will and do not care. They choose evil. God uses them in His own way to manifest His will, His plan. They could reject sin - evil - but will not and God knows this, after all, He created them and He knows the number of hairs on their heads, too.
Many people have taken the later airline flight or missed a flight, only to find that the flight they were scheduled to take has crashed and everyone aboard is dead. God did not want that 'lucky' passenger to die but He did plan for the crashed plane passengers to perish at that time. Mere mortals cannot understand this, it's God's plan, not ours.
Good people die every day, seemingly for senseless reasons. Murdered, cancer, car accidents. God's plan in action. It's impossible to prove a negative so we cannot ever know how many people do foolish things and live or have 'close ones' that could have killed them, but doesn't. Cancer tumors disappear without medical explanation. Accidents are avoided by inches. The criminal picks someone else to rape, rob and murder that night. God's plan in action again but invisible to us. We may never know how close we came to death at any given time but God knows. He is in control.
So....are there certain people who are predestined in God's world to go to hell?
Of course! But in man's world they have a choice.
I think it would be unsupportable by the Holy Bible to say that God does not ever give permission for evil to manifest itself.
If that were the case, we wouldn't have needed Jesus in the first place.
Jesus is our Shield so that God can look upon us and see no evil. If there were no evil to see, we wouldn't need the Shield.
Subsequently, Job does not attribute his fate to Satan saying: "The LORD gives and Satan hath taken away" but says: "...the LORD hath taken away". Scripture then affirms Job's testimony: "In all this Job sinned not, nor charged God foolishly". I don't think we're simple robots either. We're unfathomably complex robots :-) created in the image of the omnipotent Creator. Our choices are not made in a vacuum but are determined at the confluence of innumerable secondary causes most of which we are not even conscious. I have taken the Lord's name in vain. I did not do so with malice aforethought, but in exclamation of pain or frustration. I committed this sin because of my depraved nature and not by a deliberative choice. I think that many people justify themselves by virtue of the fact that they are not aware of any particularly diabolical motives in their lives. This state of mind is the most powerful detriment to evangalism: "I'm living a good life, I don't choose to hate anybody"
I vehemently disagree with your statement: "Good people die every day". By my reckoning, one good person died only once.
