O Harry Potter, Please Save Us All

What if Dumbledore's prediction was wrong and the Killing Curse killed Harry's soul instead of Voldemort's soul fragment in him?What if instead of an epic battle between Voldemort who was once again mortal and his fated enemy The Boy Who Lived, the wizarding world witnessed the union of two Voldemorts - both without any noses, and must have had some loose screws in their heads, and thought their version was the best?What if Hermione Granger, Ron Weasley and Draco Malfoy decided the world had gone insane and maybe they should fix it by simply blowing it up?What if this time, it was Voldemorts who begged for the 'Light' side not to destroy the world?And maybe, what if Petunia Dursley, due to her connection to the Boy Who Used To Lived, was the only hope for the world's survival?And what should Hestia Jones - Petunia's bodyguard assigned by the Order of Phoenix - do to persuade her ward to save the world, as well as find a way to defeat the Dark Lords now that the Savior of the Wizarding World was gone?All in all, it's a very messy story.
