What beloved story/character is actually a pretty screwed up story as intended by the original author?

The Little Mermaid.. it’s actually not that good as Disney made it..

In the Disney version of Hans Christian Andersen’s tale, Ariel eventually wins the heart of Prince Eric, gets her voice back and celebrates with a beautiful wedding on a boat, surrounded by her aquatic friends and family. In Hans Christian Andersen’s original story, things don’t end so rosily. In fact, the story is tragic throughout, with Ariel’s transformation to human causing her constant agonising pain, before her heart is broken when her prince marries someone else. The Sea Witch informs her that if she kills the prince she will turn back into a mermaid and live, but Ariel chooses to sacrifice herself, throwing herself into the sea and becoming sea foam.
