It's the "Circle of Life."
Kumbaya.
People who have a callous disregard for animal life generally have a disregard for human life as well-I wouldn’t trust a person who was known to cruelly kill animals any more than I’d trust a person who works at planned parenthood, even though that one is an accessory to infanticide while the animal killer is just a disgusting person.
There is nothing wrong with hunting deer, etc for food-I do it when I have the chance.
