It's either done, or it isn't.
As pointed out, it commonly occurred at sea, particularly during the 1800's and earlier (prior to instant communication and quick, fairly reliable rescue); e.g. Richard Parker was killed and eaten by the surviving crew when they made the assessment he wasn't going to make it anyway (he was one of those idiots who decided to drink seawater). By the time they decided to do the deed, the guy was supposedly unconscious, meaning he not only didn't give consent, but couldn't
Granted, they were found guilty of murder afterward, but public opinion was actually on their side in this instance - if I recall correctly, their death sentence was ultimately commuted to six months imprisonment.
Regardless, the idea is that it simply isn't done... and it quite clearly is.
you and I got different morals then.
With exceptions I ment that referring to RL survival situations.
That it does happen is an exception and so not common.
