Hi there,
Speaking about the old laws and highlighting what the main differences are and why they are morally, civilly, and jurisdictionally relevant is definitely a good idea. No need to go back to the Code of Hammurabi, but a little bit of contextualization is always useful!
Also, as a general rule to all essays, you should always avoid using the second person when you can, so go for "Mary should" instead of "You should".
Best of luck!
