In all possibilities, you do... in fact, most of us do! Even that split-second acy of throwing a stone to frighten a stray dog... that stone could have maimed the animal for life or even killed it! Would you care to know? Why, would you throw a stone at a child however much he or she may irritate you?
This only means an animal’s life holds no value for us... or, we simply take its life for granted, even as we hate anybody taking ours. Strangely enough, how two-faced can we humans get!
