I would yeah.
In the starving situation, of course I would. I mean, I wouldn't kill but if they were already dead I would eat them and continue a search for civilization. Gives their death more meaning, IMO, if it helped someone else live from it. If I was the one dead and my carcass being consumed or not meant the difference between life or death of someone else I would want them to eat me. Even if its someone I don't like, I'm not using my body anymore.
If I was not in an 'eat this or die' type of situation I think I would probably pass. Not because the idea of eating human grosses me out, more on a moral value of 'there is no reason to be eating this person, I would rather respect the dead' type deal.
If we strip away the moral value of the question and were to consider it as another type of meat on a menu that somehow never used to be a person with sentience then I would definitely give it a try. That could never happen though.
