Will the pearl destroy the family?

Juana believes that the pearl will destroy her and Kino because in the middle of the night, someone came to their brush house and tried to steal their most prized possession. Everyone wants the pearl for themselves. The doctor, so far, wants it the most. The doctor asked Kino after he was done treating the baby, "Would you like me to keep the pearl in my safe?" When Kino declined to keep in his safe, the doctor then said, "It would be a shame if the pearl was stolen before you could sell it." It seems like the doctor is going to steal the pearl. I wouldn't be surprised if the doctor comes sneaking up to his brush house in the middle of the night, with a plan to get the pearl for himself.

The pearl, even though Kino thinks is a sign of hope and happiness, is probably the beginning of the destroying of their lives. There will be more people coming in the middle of the night to try to take it. What would happen if it gets stolen before Kino gets to sell it? Also, the longer Kino has it, the more at risk him and his family gets. Juana and Kino will always have to be on guard until the pearl is gone, and if Kino is "falling in love" with this object, how long will the family actually have the pearl? All of the stress will get to Kino and Juana, and the pearl will easily destroy their lives.
