Take those canines and try to chew through a cows hide and eat the meat raw. Oh wait, you can't your teeth are not sharp enough. You can eat whatever you like but, don't use the canines for the reason you eat meat. Primates have canines too. To paraphrase John Robbins, if you put a toddler in a playpen with a rabbit and a apple I bet the child plays with the rabbit and eats the apple.
