to be fair, cannibalism does happen fairly often in nature. mothers of certain species cannibalizing their babies, in fact, is a well-documented method of managing litter sizes.
of course humans would do this too in dire circumstances, but since there's typically no necessity for us to do so, it's pretty much a net loss unless the person is already dead, in which case you then run into the ethics of what you should and shouldn't do with a corpse
Rape, murder, necro, or shemale
how in forget is that last one even amongst the rest lol
