Anandi is not responsible for what Pooja did with her life. It was she who gave in to Mannu every time despite remembering what her mother and Anandi told her despite knowing what her responsibilities towards these two women are.
Pooja and Mannu themselves are responsible for the mess they made of their life.
-------------
Let Anandi tell what she told Shekhars and what happened to Nandini.Let Nandini decide whether she should hold her mother responsible for her plight or not.
Let her decide whether she was wrong in trying to save another woman's child or not
Let her decide how much of her mother's foolishness and stupidity played role in her life ending up this way.
Let her also know what Mangala did in order to keep her close to her how she put her life in danger too.
Let her question both women.
