Perfection is not only her appearance - from small flawless legs to huge dark eyes and lush black hair. Hugo repeatedly emphasizes that when Esmeralda appears, everything lights up with some kind of magical glow. Her soul is also beautiful. It is impossible to imagine that she could deliberately hurt someone.

She was the only one from the huge crowd who pitied the unfortunate Quasimodo dying of thirst at the pillory and gave him a drink from her flask.
But she is very trusting. Luring her into a distributed net is easy. Esmiralda is too passionate about her fantasies and dreams to look at things realistically and foresee the danger.
