an amazing fact of a disaster

i just read one article on my sociology textbook
and there is a story which gives us awareness of deviance
we should use this awareness to distinguish whether an act is a deviant behavior or not

it records a disaster happening in the early of 1970's
there was an airplane which crashed in the Andes Moutains in South America
almost every passengers were dead
only 27 people survivored
unfortunately they were marooned at 12,000 feet in frezzing weather and deep snow
and they just had a small amount of chocolate and some wine
the circumstance was really bad
after few days
they heard in the radio that the search for them had been canceled

they had no idea what to do
they suffered from cold and hunger
after certain days
some people proposed that they should eat the dead crash victins
in order to survive
at first only a few ate the human meat
but soon the others began to eat too
but they refused to eat the lungs, skin, head and genitals

at the end of this terrible catastrophe
they sent 3 men to ask for help
they walked for 10 days
eventually they entered Chile by climbing over the mountains
the whole group was finally rescued

this story makes a deep impression on me
it is so hard to imagine that we should eat conspecific creature- human beings in order to survive
i think it needs lots of courage to do this
if i were in that circumstance(i hope i wouldn't hace to face up with this)
maybe i would eat the victims while crying
feel sorry for them!!!!
