In the novel, The Pearl, Kino is initially described as one who treasures his family more than anything, even money. He is patient, loving and appreciative of his young wife and son and he values them more than all else. In fact, he seems content to simply live in his very modest home with his wife and child. However, when he finds the enormous and beautiful pearl, he begins to change.
Kino’s plans for his family immediately change. He determines to marry Juana in a fancy church wedding, to buy new clothes for the entire family, to buy a rifle for hunting and protection, and to pay for Coyotito’s education. Moreover, he becomes obsessed with protecting the pearl until he can sell it and become wealthy. He becomes moved by his passions, even to the point of abusing Juana. He kills a man and ultimately loses his child and his opportunity for future happiness.
