Interesting case. It however does not adress morality. Law rarely does. I address the statutes.<quoted text>
Read "The Case of the Speluncean Explorers," by Lon Fuller. Fuller was my law professor, and used this story in teaching us the morality of the law.
Had the statues incleded exemtions for homicide by lot under duress the court would have dismissed the case in short order.
It is similar to the current lack of address by law of assisted suicide. A "morallity" that has yet to be adressed by law save states where jury nulification exists.
IN fact, had said case been presented to a jury in such a state, the defendents may have had a quick aquital.
Secualr law is as limited and flawed as sacral legalism. Neither actually address morality, just codifies (and presumes to be) community opinion.
