No--the heart of my disagreement with you is your insistence that babies are guilty of the sin of their forbears. Yes, we die physically because of what Adam and Eve did when they followed the destroyer rather than the Creator. But that is a LONG way from calling God a "murderer" which YOU did.
You persist in conflating physical death with eternal death. When you quote Romans 6:23, do you ever quote the entire passage? Why leave off: "...but the free gift of God is eternal life through Christ Jesus our Lord."?
You also neglect the context of Romans 3:23. Please, look at Romans 3:22 "We are made right with God by placing our faith in Jesus Christ. And this is true for everyone who believes..." Since babies are incapable of believing--then, I guess with you Calvinists, you are saying--"Too bad, babies, my theology says you are toast." It is clear that Romans 3:23 is speaking to the fact that it is inevitable that ALL will eventually sin.
No, it is YOU who have done that when you insist that when God takes an innocent life, He is guilty of murder. That is what the atheists say--that God "murdered" His own Son. Only God, who gives humans their lives, has a right to take them without cause. Did Abraham question God about the order to kill Isaac? No, he apparently assumed that God would revivify Isaac. He knew that the holiness of God is total. YOU apparently question that and make up your theology around your doubts.
Murder is decidedly evil-no doubt about that. It is why God prohibited human-to-human killing without just cause. When it is without just cause, that's when we call it murder--rather than killing, such as in self-defense. No--the biggest injustice is to malign the holiness of God by stubbornly insisting that your theology could not be wrong, and that if babies die, it is because they are somehow guilty of the sin of their antecedents.
