This is why I have suggested that there is no difference in culpability between anger and murder, lust and adultery. There is only a difference in consequence. The authority to carry it out is granted by God. However He is not responsible for sin. Sin is rebellion of the will, and is independent of any actual deed.
Sin exists apart from law.
But sin is not imputed without law. Perhaps it is possible that the universe is only non-mechanistic as it applies to living beings, but is completely mechanistic as it applies to inanimate matter and energy. If I will to kill another person, God twiddles with the universe to make that happen. I am responsible for the action because God granted me the authority and he confirms or upholds that authority by making what I will happen. Here is the problem I found and I am curious what you would do with this fact.
