I thought this up a while ago, and I've been trying to decide how it would turn out ever since. For the life of me, I can't decide.
Imagine, if you will, that you're stranded on an alien planet. By some miracle, the atmosphere is breathable and the wildlife isn't trying too hard to kill you. Unfortunately, you're running low on supplies and there is only one single edible thing on the planet: the natives. They're intelligent, friendly, and peaceful. They have done you no wrong. So the question comes down to this: murder an innocent or slowly starve to death.
I want to think that I'd do the noble thing and die, but I simply can't know for sure.
actually, if the natives have tissue that you can eat that lets you absorb the nutrients that you need to survive as a human, then they had to get those nutrients through some means, which you could repeat and spare the locals.
I win.
No you don't.
For those trying to knock down the hypothetical, here's a hard-science version. The alien planet's life does not use an amino acid which is essential for human survival. Without this amino acid, you die. (Since there are eight to ten amino acids which humans beings cannot survive without, depending on which text you consult, it would hardly be surprising.) Now, it turns out that the planet's life forms do not use methionine, threonine, or isoleucine, three amino acids without which we humans cannot live. Eat these amino acids or die. The only beings who use these three amino acids are the alien's sapient species, who modify other amino acids to form them. These amino acids are used to make a protein inside the sapient being's cardiac muscle.
In order to get the amino acids you must have to live, you must eat the cardiac muscle of these beings. In addition, the beings have a feudal culture which forbids any desecration of their dead; under no circumstances will they give you their dead, and they will fight to the death to protect their dead. Neither you nor the alien sapients are able to synthesize these amino acids in the lab, in your case because you do not have any know-how, and in their case because their culture is not technological enough. Nor do you have the time or resources to try this on your own. Maybe a future expedition can study the biochem of these creatures and learn how they work, but you're just a lonely pilot who is -very- hungry and far from home.
There you go, a hard science version to get to the same question.
