These animals should be hunted for necessity, not for cultural purposes. There are many here that agree that human life should be preserved and it is a far stretch from killing a whale. So, would you support cannibalism? Do you think that if every part of a human body is used that it's ok to hunt and eat them? Cannibalism once was a cultural activity but we don't have that around much anymore do we? Cultural aspect is not a good enough reason in my opinion.
We have to eat, and I eat meat. Therefore, I always kill animals for necessity (or someone else does it for me like if I buy meat at the market).
Cannibalism was not done for food purposes (except like on lost at sea rafts, or wrecked planes) but more as a way to aquire the strenght and courage of the adversary. I dont think humans hunted humans for food. They were casualties of war. If some tribes in amazonia are still canibalistic, well, It's none of my business. It's their culture.
