I believe honor and dignity would be flushed down the toilet in this situation, anyway why not? I don't eat people because I don't have to, but given the chance in those circumstances hell yeah. Self-preservation over honor and dignity.
I guess i would probably turn it down, i mean if i did get out afterwards i would probably be imprisoned for cannibalism.
Many people say no, because they have not been actually in that situation, it's similar to those people who get lost in the desert, and drink their own urine to survive, they say that they won't do it, but when actually in those sorts of situations, you try to do whatever it is to survive, so i would say I'm not sure.
