The beginning of the novel show the goodness of Kino and Juana explicitly. Kino works the "land" to provide for his family (farms the oysters in the sea) while Juana provides maternalistic comfort to both her baby and husband. They live simply and humbly. The appearance of the pearl is the beginning of the destruction of that harmony as Kino dreams of bigger and better things for his family (not a bad pursuit but full of conflict.) The scene with the market people when Kino tries to sell his pearl shows this conflict.
