The bird and its companion, the hat, are destined to be rulers of the world. In ancient greek, the bird is "life". If you kill the bird, there is no more bird. And if there is no more bird, life ends, as the birds attack the world, until the last human is killed. The bird will rule, and if you questions its motivations, then, oh well- bye bye you.

Respect the bird.
Or die.
