Most probably, Abraham would not have sinned if he had killed Isaac because he was carrying out the command of God. All people have sinned against God (Romans 3:23) and are, therefore, worthy of death (Romans 6:23). Isaac was a sinner and was deserving of death the same as us all. Therefore, if Abraham would have killed Isaac, then he would have been carrying out the command of God to execute Isaac, which would have been according to the law of God in which all sinners deserve to die (Genesis 2:17, Romans 6:23).
