Animals are more than ever a test of our character, of mankind's capacity for empathy and for decent, honorable conduct and faithful stewardship. We are called to treat them with kindness, not because they have rights or power or some claim to equality, but in a sense because they don't; because they all stand unequal and powerless before us.

In any case I just cannot imagine attaching so much importance to any food or treat that I would grow irate or bitter at the mention of the suffering of animals. A pig to me will always seem more important than a pork rind. There is the risk here of confusing realism with cynicism, moral stoicism with moral sloth, of letting oneself become jaded and lazy and self-satisfied--what used to be called an 'appetitive' person.

When you start with a necessary evil, and then over time the necessity passes away, what's left?

If we are defined by reason and morality, then reason and morality must define our choices, even when animals are concerned. When people say, for example, that they like their veal or hot dogs too much to ever give them up, and yeah it's sad about the farms but that's just the way it is, reason hears in that the voice of gluttony. We can say that what makes a human being human is precisely the ability to understand that the suffering of an animal is more important than the taste of a treat.
