Quote #10

"The Imperius Curse," Crouch said. "I was under my father's control. I was forced to wear an Invisibility Cloak day and night. I was always with the house-elf. She was my keeper and caretaker. She pitied me. She persuaded my father to give me occasional treats. Rewards for my good behavior." (35.133)

We find Mrs. Crouch's decision completely baffling. We get that she doesn't want her son to rot in prison, but how is this treatment truly any better? He's not free at all, certainly, and it's inevitable that something is going to break Barty Crouch, Sr.'s concentration at some point, leaving the son able to do whatever he wants. All we can conclude is that love makes people do the strangest things.
