Was Maisie wusste

Henry James masterfully captures Maisie's innocence while exposing the adult conflicts around her. I wonder what inspired his approach to narrating from a child's point of view.

The adults' selfishness and manipulation made me question how childhood innocence can survive in such environments. Was this portrayal meant to evoke sympathy or critique society?

The conclusion leaves a lot open to interpretation, and I kept wondering whether Maisie finds peace or remains vulnerable. How did others interpret her future after the story ends?
