There was a place for cannibalism here, the greatest survival story of the twentieth century (and, no, I am not forgetting Shackleton):
Uruguayan Air Force Flight 571

The bodies of our friends and team-mates, preserved outside in the snow and ice, contained vital, life-giving protein that could help us survive. But could we do it?

For a long time, we agonized. I went out in the snow and prayed to God for guidance. Without His consent, I felt I would be violating the memory of my friends; that I would be stealing their souls.

We wondered whether we were going mad even to contemplate such a thing. Had we turned into brute savages? Or was this the only sane thing to do? Truly, we were pushing the limits of our fear.—Survivor Roberto Canessa
