In recorded history, has it ever been done? Before it was deemed cannibalism, was it done? Why or why not? What innately keeps man from doing this? Even during times of slavery, this did not happen. Why not? The slaves were seen as property and livestock. Why wasn't this done?
Cannibalism has occured in many societies as an innate part of their culture.
Endocannibalism is when people eat deceased members of their own community, exocannibalism is when the eat people from outside of their community.

I don't think that at any point humans were raised by other humans for the specific purpose of being eaten, but that's irrelevant as no other meat eating animal raises its own food either.
Cannibalism occurs in many other animals- sometimes it's sexual cannibalism as in the black widow spider and the praying mantis.
Other times it tends towards cannibalism of ofspring- pigs and hamsters, for example, are both known to eat their young. I don't know why, though.
I also don't know if there are examples of other animals attacking and eating other adult animals, except maybe in cases of food shortage.
Humans tend to cannibalise for a specific reason- hunger, revenge, respect.
That may be because humans are distinct from other animals in that they have a high capacity for abstract thought and can develop reasons for why they do or do not do something. With this capacity comes a perception that other humans are different from food animals, and so the consuming of them is viewed differently.
This may not always have been the case- I recall reading some years ago something about a discovery of early human bones. The knife marks and heat charring indicated that the person had been cut up and cooked, but the bones were found in an area with a high concentration of similarly treated food animal bones.
This would suggest that not only was the person eaten, they were viewed as being on a par with other food animals.
I'll try to find the article, but it was many years ago.
