Would you ever become a cannibal?

At any rate if you were in a situation like stranded somewhere remote not knowing when or if you'd get rescued, Food is scarce and all you have are the people or group of survivors with you. Rather they are alive or dead would you consider them as food to survive or would you just accept you may die yourself. Also knowing you may die and be food to the others would you stil not eat someone or be a cannible to survive. I know this can be a tough questions because it tests morals, religion, diets etc (vegetarians and vegans for example) but I do know desperate times call for desperate measures. And sometimes survival mode is all you have. 

I forget the name of the movie but I saw it where an airplane crashed in the mountains and they ended up eating their dead friends to survive. It was based on a true story. It was a great movie if I remember the name I'll edit it into the post. 

EDIT: movie name is "Alive" thank you Amanda 👍
