Ethically I think it is very wrong to raise then kill animals for others to eat them! But like the saying goes; one man's meat as another man poison! People who do the raising and slaughtering of animals purely do it for economic reason; survival! They are not interested in building bond or eternal relationship with these animals so the emotional attachment is never there for most and if its there on rare occasions their quest to survive and just move on overrides their emotional state! But after it all said and done, that's life! It will surely happens to us all; its like a cycle! I don't know what law can be written to forbids the raising and killing of animals for consumption except if we are all vegetarians and what about the life cycle of all these plants we raise then cultivated to eat as vegetarians? That right there is the twist of life my friend! Lol!
