But that's the point. We have intelligence and morals. It's what we base our humanity on - achievements in the realm of mathematics, engineering, physics, chemistry, etc. We cannot use "well we're animals" as justification for intellectually reprehensible acts like torture. A cogent human has no business factory farming, ie. torturing animals for tastebud entropy unless it's by necessity. Hunting and eating animals is a blurred line but I'd generally say its OK given that it's a lot more filled with respect and lack of torture than the meat industry.
