Because they were happy before he found the pearl. He wanted it to be that way again. Whether or not it can be is perhaps in doubt, but... he is going to try. The Pearl brought him nothing but pain and complication... he is losing everything he loves, and so he throws away what he thinks is the cause of it all.
Juana wanted kino to throw it back into the ocean.
Kino reacted that way because he thought that the pearl waspart of his soul as it says in the book. So if the pearl left his soul would leave him too. Also he did not want to wealth to get away that easily and by that time Kino was a greedy guy. THis i because all he thinks about is the pearl and what he would get like a rifle. So he didn't want that to happen, so he acted fiercely just to get it back because he wanted his wealth and did not want the chance to pass by. I hope it helped.
A rifle, to get married in a church, and to give Coyotito an education.
Kino wants to use the money for his son Coyotito. He wants to give his son a better life and a better education than he and his wife, Juana, has. But after tragedy strikes that reason is no longer there. They do not want the money for themselves nor do they want the pearl in their possession any longer.
