By pitying Helen, her parents were acting as if her condition would change which would be lying. Her condition was never going to change and so if they continue to pity her she would eventually be helpless when they are gone. By leaving her helpless, she's not capable of doing anything, ultimately making her look ignorant; therefore by pitying her, they lie and tell her she's stupid and ignorant.
