Philosophy Lite- now, with fewer calories!

There's a 2 week class called Moral Foundations of the Law, led by the dean the 1st week, and co-led by Bork week 2. (Exciting! I'll get a chance to meet my idol! But...) The problem is, that when you have a forum of 70 people, mostly from different educational backgrounds & many professing different ideologies, you get nowhere unless A) The matter at hand is limited and clear, and B) terms are defined from the beginning.
Our scenario was about spelunkers-turned cannibals (spelunkers are starving to death in a cave & they get word over the radio that they will die of hunger before they can be rescued. They form a "social contract" whereby they agree to roll dice & eat the low-roller. They are rescued days later & tried for murder. This country only has 1 penalty for murder: death. Questions: Should they be found guilty of murder; is it hypocritical of the cheif justice {this case was appealed to the Supr. Ct. of that country} to say, guilty, but recommend executive clemency?, etc.) As you can imagine, we got a barrage of "I thinks" and "In my opinions" but there was almost nothing solid to refer to (cf "Do you have text for that?) I hate this class. 2 of my fellow TACers use it for a study hall. I kid you not: Hobbes' "state of nature" was being confused with St. Thomas' idea of a "natural right" WITH RECKLESS ABANDON and it was heartwrenching. Someone suggested that instead of murder, the spelunkers could have waited for the 1st person to die naturally and then eat him instead. Many objected. The dean, rightly, asked, "Do you object on moral grounds or from repugnagce to eating human flesh at all?" One student then made up some vague, unsubstantiated, and incorrect reference to "Aquinas, like, asserts that humans have, like, dignity and so you can't, like, eat their bodies under any circumstances." To which fellow TACer & I replied that a dead body is really just a corpse, so you're not eating a person. And if that's the only way you're going to live, you have the right to do it. Then some hotshot yelled angrily in our direction, "Well, I believe in the resurrection of the body! You can't eat a dead person."
Sigh. But wait- there's more!
"Humans don't naturally have dignity anyway," pipes up another. "It's a social construct."
