Exactly: you have to act morally, as well as perceive morally. Or, more to the point: just carrying out the actions prescribed by morality does not make you moral — you need to do it for proper reasons too. Otherwise you’d be forced to say of robots, animals, and more interestingly, immoral people, that they can be moral simply by carrying out a specific action.

Which, once more, leads back to empathy. It’s at the heart of morality — there is no morality without empathy, quite simply because morality, in so far as it it concerns relationships between people, implies the possibility of putting yourself in the other persons position and thus to accept their view as fundamentally on a par with your own.
