If there is any curiosity about why there is so much cruelty to animals present in Asia, one only need look back to WWII. The Rape of Nanking, the unbelievable atrocities in the Philippines, Bataan Death March and other incidents throughout the Pacific, the beheadings and starvation of POW’s were of a caliber even Hitler never thought of.
Life is held cheaply in this area of the world and animal life has no value except to be eaten and as for torture before death, well it can be seen how that evolved. Evolved is not the right word- it’s been going on for centuries! You could say the cruelty tactics have evolved for the enjoyment of the observer!
