The Spartacus of SeaWorld: Who knows, of course, if Tilikum the SeaWorld orca had a motive in killing his trainer, Dawn Brancheau, and withholding her from rescuers. But an impulse to attribute humanish motives to animals is ancient and irresistible. I don't think we do it from egocentrism, but rather from fellow feeling and analogy. We are, after all, animals, too. We have an inner life, for which there's no external proof. Why shouldn't they?
