If slaughtering animals for food is no wrong then for sure the same should apply to raping, drug addiction,murder and savage killing of fellow human beings. Man has no right to kill animals for food and it would be a shame of the highest order to kill for the pursuit of taste. Would the person like to see the flesh of his child or any of his family member in a serving plate. It is the same feeling one should have before he consuming the meat. Emotions could rule high on the death of a family member for the fact that there was a deep sense of attachment and bondage.
Every creation has it.
I definitely believe that animals have equal rights as we do. Above all never think that god had created such animals to be only killed for food for man. It follows the theme that what our ancestors did to live a million years back cannot be taken as the right path of life. As time advances , we have to question every action. My message is simple.
