Will the pearl destroy them?

Juana thiks that the pearl will destroy them because bad things have happened since they found the pearl. The pearl is giving them bad luck. The doctor has come over a lot to "help" the baby,but he really just comes over to see if he can probably steal the pearl. I think that in the end the pearl will be either stolen or Kino will do something with it like throw it back in the sea. The pearl has done no good to the family!
