Eating dead people could be a good way to increase protein in the diets of poor people. Would also reduce the costs of cremations and burials, except for all the old bones that might be left lying around the back of the house after grandmar passes away.
People need to be more positive on this subject instead of raising irrational cultural taboos as an excuse to condemn the practice. Be more positive and look at the plus side of things. A lot of people currently raising dogs for the table could be more efficiently employed caring for the elderly and sick. The dogs would appreciate it I am sure.
