You: No, but that's a completely irrelevant point. All it proves is that the judicial system is not perfect, not that the law is wrong. The people are not morally against prosecution, they are just unable to get it an all cases where it would be desirable.

Aaron: None of this has anything to do with my original point.

You: Of course it does. If people create laws which appear to be moral, and those laws are created for pragmatic reasons, then there is no need for God to be an example of good. Morality will work itself out.

Aaron: I have to admit that I'm completely lost. If you are saying that morality can evolve, then I must disagree. If, on the other hand, you are saying that the legal expression of people's morality changes over time, then perhaps, this is nothing more than is part of God's plan.

You: There's no way to tell the difference between a natural process and one that is "part of God's plan."

Aaron: All things are part of God's plan.

You: But how can we tell that? You keep introducing concepts that have no philosophical usefulness.

Aaron: Fine. If you are so tied up in making this a formal logic problem, then perhaps you should try this argument on for size.
