The Selfish Child
It appears that when Barrie first came up with the idea for the character, he saw Peter as a fantasy. Living selfishly and heartlessly yet innocent was appealing to Barrie, which is why he was able to turn the story into a sentimental fairytale. Later, he wanted to grow up and develop true empathy and realized that he could not.
But both versions of the story keep Peter as the ideal selfish child. This makes it easy for Peter Pan to turn into a villain instead of a hero. The true story of Peter Pan is a divine fantasy combined with your worst nightmare. Furthermore, you can look at the author in the same way. Is Barrie a storytelling genius, or a twisted man who ruins the lives of children?
