The practice of eating animals is a culturally ingrained habit. If you're in the U.S., you might dine on pigs, cattle, and chickens; if you're in Mexico, you might feast on goats; if you're in parts of Asia, you might devour dogs and cats. We humans have a funny way of judging other cultures for what we think is cruel, despite our own commitment to cruelty. To the animals, it's all the same.
