Now the tension which had been growing in Juana boiled up to the surface and her lips were thin. "This thing is evil," she cried harshly. "This pearl is like a sin! It will destroy us," and her voice rose shrilly. "Throw it away, Kino. Let us break it between stones. Let us bury it and forget the place. Let us throw it back into the sea. It has brought evil. Kino, my husband, it will destroy us." And in the firelight her lips and her eyes were alive with her fear. (3.75)
Here it is Juana, not Kino, who has the incisive ability to recognize evil.

"Hush," said Kino. "Do not speak any more. In the morning we will sell the pearl, and then the evil will be gone, and only the good remain. Now hush, my wife." (3.78)
It’s unclear whether Kino is patronizing his wife by calling the pearl "evil" or whether he truly acknowledges its nature.

And the beauty of the pearl, winking and glimmering in the light of the little candle, cozened his brain with its beauty. So lovely it was, so soft, and its own music came from it – its music of promise and delight, its guarantee of the future, of comfort, of security. Its warm lucence promised a poultice against illness and a wall against insult. It closed a door on hunger. And as he stared at it Kino's eyes softened and his face relaxed. He could see the little image of the consecrated candle reflected in the soft surface of the pearl, and he heard again in his ears the lovely music of the undersea, the tone of the diffused green light of the sea bottom. Juana, glancing secretly at him, saw him smile. And because they were in some way one thing and one purpose, she smiled with him.
The pearl is neither evil nor good. It is simply what the characters choose to see.
