I don't think it is a right or wrong situation. Definitely whacking someone for some dinner in modern day USA is not right, or even something that is thought about.
You change the setting to a plane crash high in the mountains with no other source of food and meat is meat. You eat or die , I think you're basic survival instincts would take over and right or wrong turns into dead or "Alive". If it meant living another day hells yeah pass the salt and pepper please.
I know people around the world eat some funky repulsive shit anyway, it may not be so bad compared to some things.
