The Deathly Hallows (Rowling, 2007)

The theme of the last sequel of the Harry Potter stories is the way to approach death with wisdom rather than the denial of it. The wizarding folklore of the Deathly Hallows delivers the message of respect for others and the acceptance of mortality as the wisdom to overcome the fear of the death encountered by mortal beings.
Aberforth Dumbledore, the younger brother of Dumbledore explains to Harry the reason that Dumbledore regrets his deed to pursue the ideal world of wizards and witches with Gellert Grindelwald, his friend who is genius magician but lacks the respect of Muggles, is the death of Dumbledore’s weak younger sister. The sacrifice of Harry’s mother keeps Harry alive while the death of Voldemort’s mother due to the loss of hope breaks the link between Voldemort and the members of his community. Distrust of others and the abhorrence toward his Muggle father who abandons his mother, leads Voldemort to kill others ruthlessly and to dread being killed. The respect of family members and friends with diverse characters is the fundamental condition to build a decent wizarding world.
Harry, Ron, and Hermione encounter difficulties and contradictions during their quest to find and destroy the horcruxes. Harry experiences loss: The death of Moody, Dobby, Fred Weasley, Lupin and Tonks; the suffering of Hermione from being tortured; and the injury of George Weasley, who loses one ear forever. However, Harry finds the way to accept the death of his loved ones while keeping the memory of them when he is attacked by Voldemort in their final duel. The moment Harry faints, he encounters all the people who he misses desperately. Ironically, Voldemort attempts to kill Harry without realizing that he kills his own soul inside Harry.
The production of Horcruxes is a defensive way for Voldemort to protect his life from enemies while the pursuit of the Deathly Hallows is an active way to possess the magical treasures which are believed to make wizards and witches avoid the death through beating challengers, resurrecting the dead, and hiding their owners from risks. However, the folklore of the Deathly Hallows reveals the lesson that the death is a natural phenomenon and should be accepted. Voldemort who lacks wisdom tries to achieve the Elder Wand, the wand of the greatest magicians that beats all challengers. Harry finds that Dumbledore and Snape protect the three Deathly Hallows: the Elder Wand, the Resurrection Stone and the Invisibility Cloak. Neville Longbottom, who was once considered the weakest, destroys Nagini, Voldemort’s pet snake that is the last horcrux. The quest of Harry to fight against Voldemort is over and Harry’s scar does not give him any more pain. Harry marries Ginny and Ron marries Hermione. Harry also becomes the god father of the orphan boy of Lupin and Tonks.
