“Besides," said Miss Abbot, "God will punish her: He might strike her dead in the midst of her tantrums, and then where would she go? Come, Bessie, we will leave her: I wouldn't have her heart for anything. Say your prayers, Miss Eyre, when you are by yourself; for if you don't repent, something bad might be permitted to come down the chimney and fetch you away.”
What does the phrase “I wouldn’t have her heart for anything” mean in the context above?
Thank you very much.
