To be honest, I really don't know either, athelos (although we've had a mighty interesting after-dinner discussion with friends on this topic a couple years ago and most were "grossed out" and several thought it was "sinful" and/or "immoral").
While I can't be 'sure' of anything, I do suspect that I while I may have a hard time doing it, no matter the circumstances nor how hungry I was, the urge to live burns strong in me. But add my or someone else's child to the mix and have them starving, I strongly think I would not hesitate at all. (Time for the 'morality' of my actions - or the lack of - later when the little ones are home safe and sound).
PM - It's lovely to be able to share thoughts and opinions without there always having to be a solid 'black/white', 'right/wrong'' line -
I've never found your opinions to be "forceful", honestly.
