Chapters 5 and 6
Juana tries to throw the pearl away and Kino gets angry at her attitudes. Finally, he ends up hitting Juana and killing an attacker. Since he killed the man only because the man intimidated him, the death was a murder. The next day, the whole family attempts to leave the town to escape penalties. They try to avoid the trackers by sneaking out silently. However, as Coyotito cries, one of the trackers shoots him and Coyotito dies. Juana mourns and Kino feels guilty. At the end, they together throw the pearl to the ocean.
The pearl was a real evil to test the greediness of human beings. If Kino had sold the pearl to the dealer on the first hand, then the whole journey and the death of Coyotito wouldn’t have happened. Because Kino’s desire toward the pearl was so mighty, he put all of his efforts into himself, protecting the pearl. This made him to lose a good reputation as a husband and a townsman by hitting her and murdering another townsman. The pearl just totally ruined the whole family.
