What of compassion?

"You find out something important about a person when you see how they treat those who are weaker than them. But you find out most about a person when you see how they treat those who have absolutely no power; those who are helpless....the most obvious candidates for this status are animals." —from The Philosopher and the Wolf by Mark Rowlands

What does it say about our species that we subject helpless creatures to short miserable lives that end in brutal deaths so that we might enjoy the taste of milk, cheese, eggs, and meat? If we do this to them for so small a reward, then what might we do to one another for a much greater reward—if we thought we could get away with it?
