I fail to see how Kino is greedy. Kino's dreams of rifles and new clothes were for his family. He wanted a rifle and a harpoon so that he could obtain food for his family. He wanted new clothes so that his family would be accepted by society. Most of all, he wanted Coyotito to get an education so that Kino and his people would learn the truth- how they've been lied to by the colonists. If Coyotito got an education, he would be able to see how wrong everything was, and through him, Kino.
