I see where this is going, and I am hesitant to respond, simply because it seems that you have no understanding of the concept of what sin is. You do not know how it works, and you do not understand righteousness. This is apparent not because you disagree, and have a legitimate concern which is, the view point that God purposely used Pharaoh as an undeserving pawn, hatefully. Rather, because you make the statement, "The murder of innocent children would make God out to be a Psycho Murderer." With you lacking basic understanding in these things along side of assuming God is a Psycho Murderer, I am afraid you have no interest in learning and understanding but rather would like to prove forcefully your opinion that God is a Psycho Murderer. I for one can not debate you regarding rather or not God is a Psycho Murderer . I'd be foolish, clearly you have no reverence towards the thought that you at minimum could be wrong and if you are that is an extremely detrimental thing to say. However, not only that it is my opinion that your view is biased and shallow even while lacking deeper insight. I've already said many things, I hope that you can reread it for better clarity, as I explain in detail how God goes about hardening a man's heart. What that means and how it affects the individual who has chosen to be outside of the proclamation of God's Divinity. I'll leave you with this, if a person has cancer on a part of their body and the doctor feels there is no other option other than to amputate the entire body part given the circumstance: would you feel that the doctor was a Psycho Murderer because there was some non cancerous tissue surrounding the cancerous growth? Would you accept the doctors perspective that the healthy tissue, will in fact likely become cancerous in the future if not precancerous because of the current state of affairs that the patient was currently in? Sin is a cancer. It can not be spared, until then it will be treated in anyway God sees fit. But know in the end because it challenges the wholesome and perfect operation of God's Kingdom, it will be destroyed, and the only way to prevent that, is to repent, turn from it, and be cleansed through the blood of Christ. If you don't like that idea, well you can do what others have before you and attempt to be your own god. But there is only one God and all who oppose him will be dealt with justly. For the sake of those of us who love him, and cry out for a sinless world. Children are conceived in sin, and God does not deny that their are generations of sinners who hate him and do not keep his commandments visiting their sins and dealing with them however he sees fit. It's awful, it's horrendous that the world is in this current state, but it is not God's doing, it was man who decided to be their own god and it was man who got spiritually taken over by the adversary and used as a puppet to destroy all that is righteous and go against God and become his enemy. Just as any being who is forced into war has to protect their kingdom against the enemy, so does God. Yet he is the only being who has power to wipe the enemy out immediately but instead chooses to suffer long so that even one might come to repentance, and be spared instead. Sin is a cancer, it takes over there is nothing that can stop it or control it but the law of God and obedience towards it. It ensures that no one is hurt. Because currently the wages of sin is death then death remains until sin is swallowed up in victory. Unfortunately, that includes any flesh that has been exposed to sin which we all are born in sin. All of our bodies can be subject to death. Death is not something to fear, when you are a Christian, raise your children in the fear of the Lord. Again, it's awful, but innocent is an improper adjective in this case if you understand Sin.
