Why did Rachel steal her father's idols? (Genesis 31:19)

In Genesis 31:1721 NKJV we read:

17 Then Jacob rose and set his sons and his wives on camels. 18 And he carried away all his livestock and all his possessions which he had gained, his acquired livestock which he had gained in Padan Aram, to go to his father Isaac in the land of Canaan. 19 Now Laban had gone to shear his sheep, and Rachel had stolen the household idols that were her father’s.

Clearly though Laban had idols. Though Jacob being a man of God why would his wife steal her father's idols?
