The hypothetical never said you couldn't cook it. I'm honestly shocked at all the morally upright people that think they'd be willing to starve, knowing there was perfectly good meat right there that wouldn't know the difference. Even if it only meant a few more days of survival, I would never give up hope of being rescued and would try to live as long as possible.
So yes. No question, I would do it. Maybe I'm just not as squeamish as other people, but I think of it as "would I want someone to eat my body for a chance of survival?"And the answer is without a doubt yet, especially if it's my family, no matter how squeamish about cannibalism they may be.
