Harry Potter and the Prisoner of Askaban is the third book in Rowling's series in which Harry prevents Lupine and Sirius from committing a mortal sin by saving Wormtail. Another transition occurs in the last book, Harry Potter and the Deathly Hallows, when Harry leaves Hogwarts to fight Voldemort in the Forbidden Forest and sacrifices himself for the well-being of his friends. Indeed, there are many of Harry's acts that can be linked to the Christian belief of 'good' and his understanding of altruism or as Knudslien expresses it: "Harry[.] demonstrates Christian values ​​in many of his actions throughout the series. ” (151). However, critics question whether Harry Potter is the same as Jesus. Thomas argues that the “[…] portrayal of Harry as Jesus […] sometimes seems Procrustean. Harry's rule breaking and mischief [...].” (366) Over the course of the series, Harry wanders around Hogwarts several times at night, which is a clear disregard of the school's rules. Also, Harry uses the Sectumsempra curse on purpose, which seriously injures Malfoy in Harry Potter and the Mudblood
