My theory.... Emma transformed into the Dark Swan, when she learned that the price for destroying the Darkness was Hook's life. She became a villain in hopes of saving him, from his unfortunate fate. Which would explain, why she is so possessive of him in Storybrooke. The Dark Swan's plan to mold Gold into a hero, is probably her futile attempt to fight Fate. We already know that villains do not get happy endings, because they go about getting them the wrong way.
