The Harry Potter franchise follows the adventures of Harry Potter, starting from age eleven to the time he is seventeen years old. Throughout his years at Hogwarts, Harry Potter captures his coming-of-age along with the stories of Harry’s two best friends, Ron Weasley and Hermione Granger. The trio of Gryffindors combat evil every year of school and then go off on the run to complete their mission of destroying Horcruxes to defeat Voldemort forever, rather than return for their seventh and final year of schooling.
From the first moment Harry learns about the four Hogwarts Houses: Gryffindor, Slytherin, Hufflepuff, and Ravenclaw, he is made very clear that Gryffindor is the house of the brave, while Slytherin is the house of evil. Harry is quick to believe what he is told, as he is warned that Voldemort, the man who had killed Harry’s parents, had been in Slytherin. Harry’s desperation to go anywhere other than Slytherin comes from Draco Malfoy’s constant bullying and is backed up by the belief that the Slytherins are all evil. However, there were plenty of moments throughout the franchise that proved that people from other houses, even Gryffindor, could be villains or dark wizards. Although Slytherin had the worst reputation, were the other houses always that much better?
10 Peter Pettigrew Betrays the Potters
Back during the Marauders Era at Hogwarts, Peter Pettigrew had been the fourth-best friend to James Potter, Sirius Black, and Remus Lupin. Joining them on adventures and becoming animagi, James, Sirius, and Remus never would have thought Peter capable of betraying them. However, Peter’s betrayal is one of the biggest pieces of Harry’s backstory.
Peter Pettigrew Lacked Gryffindor’s Bravery and Loyalty
Gryffindors are known for holding or valuing certain traits, such as bravery and loyalty. However, by turning against his friends and being tempted by Voldemort’s influence and power, Peter showed he had neither. Peter’s actions resulted in James and Lily’s deaths and Harry growing up an orphan. Rather than come clean about his actions later, Peter blew up a street full of Muggles, allowed Sirius to take the blame, and transformed himself into a rat for twelve years while Sirius rotted in Azkaban. Peter does not exhibit any Slytherin traits either, and it is a mystery what the Sorting Hat must have determined to decide on a House for a character who portrayed none of the best traits of the four houses.
9 Hagrid and Ron Judge All Slytherins Negatively
Hagrid and Ron are two of Harry’s closest friends, and two of the first people he meets and spends time with in the wizarding world. However, both make it clear early on that they believe all Slytherins to be nothing more than liars, cheaters, and evil wizards in training.
Hagrid and Ron Go too Far in Blame
They certainly have history on their side, to a degree. Voldemort and most of his Death Eaters are from Slytherin House. In recent history, all dark wizards have come from Slytherin. But, that does not mean that all Slytherins are dark wizards. Hagrid and Ron’s claims are better stated toward grown adults, not young children. When Slytherin students are anticipated to be evil from the moment they are sorted at eleven years old, it is nearly a self-fulfilling prophecy that they will go dark because everyone expects it of them. Hagrid and Ron’s declarations against the Slytherins that Harry, Hermione, and most of the Weasley family tend to agree with are far too judgmental. Slytherin traits are considered to be resourcefulness, cleverness, ambition, and determination, none of which are necessarily bad things. At times, Gryffindors can jump to conclusions about people just as much as anyone else can.
8 Dumbledore Lies and Manipulates Harry
Dumbledore is meant to be a kind, grandfatherly figure for Harry. He looks out for all the students and claims to be on the right side of war and moral compass. However, Dumbledore keeps a massive secret from Harry for the entire time they spend together, all the while manipulating Harry into being prepared to die.
Is Dumbledore Really a Good Guy?
While Dumbledore’s past does acknowledge his more positive Gryffindor qualities as he defeated Grindelwald, he also spends most of his time keeping his biggest secrets to himself, telling everyone the information they need far too late, and hiding a mysterious backstory about his brother and late sister. Dumbledore is considered to be as Gryffindor as one could get, never frightened in the face of evil, and considered the only man Voldemort ever feared. But, he also had a power-hungry streak in his youth that may not have entirely gone away if the incident leading to his cursed hand said anything about it.
7 Xenophilius Lovegood Turns in Harry, Ron, and Hermione
There is not much of Xenophilius Lovegood in the Harry Potter franchise. He is known as Luna’s whimsy father who runs the Quibbler newspaper, but otherwise, his biggest use is to tell Harry, Ron, and Hermione the story of the Deathly Hallows.
His Desperation for Luna’s Safe Return Results in the Wrong Actions
Xenophilius Lovegood was sorted to be a Ravenclaw, and their attention to intelligence of all sorts goes against him when he chooses to lean on the Death Eaters for the safe return of his daughter. The Death Eaters had taken Luna in response to what Xenophilius had been writing in the paper. So, when Harry Potter shows up on his doorstep, it is basically an opportunity that can not go to waste. Except, his refusal to think it through is particularly unsettling. He is desperate, but how desperate is he to betray his daughter’s closest friends?
6 Sirius’ Fatal Prank on Snape
Sirius and Snape’s mutual hatred that was initially introduced in Harry Potter and the Prisoner of Azkaban goes all the way back to their time as students. Sirius was a Gryffindor, while Snape was a Slytherin, but that was the least of their issues.
Sirius Lets Snape Nearly Die as a Joke
Although the Gryffindors have a way of being loud, and their rivalry with the Slytherins is legendary, Sirius steps away from his positive Gryffindor traits when he encourages Snape to walk into the den of a werewolf. Sirius is well aware of the dangers that could come from Snape being near the Whomping Willow, and only due to James coming to Snape’s rescue did things not go horrendously wrong for everyone involved. If Gryffindors are supposed to be the heroes, even if Snape was a young villain to many, encouraging him to walk to his potential death was not a very heroic thing to do. While Sirius seems to recognize he had gone too far as an adult, it does not excuse his childhood willingness to risk a life.
5 Ron Abandons Harry and Hermione
In many ways, Ron embodies the Gryffindor spirit. He is brave and bold, always willing to step into danger side by side with Harry and Hermione. Ron has plenty of positive qualities and, for the most part, plays his role as the best and most supportive friend very well. But, loyalty is not always Ron’s best trait.
Ron Crosses the Line in War Times
Having grown up with a loving family and food always readily available, living out of a tent with the scraps they could find, and wearing a Horcrux that heightened his biggest fears and anxieties, and it was basically a waiting game to see how long it would be before Ron ultimately snapped. Although Ron does eventually return to join his friends, Ron’s abandoning of them and his insults to Harry just before he goes are not in the name of Gryffindor loyalty. Although no Slytherin characters were in a similar situation, This is the second time in the series that Ron turns his back on Harry, the first being when his jealousy got the best of him during the Triwizard Tournament.
4 Percy Turns Against His Family
Percy is far different from the rest of his family. Significantly more high-strung, Percy places academics and his ambition for his future as higher priorities. Given those are more Ravenclaw and Slytherin traits, it is confusing as to why Percy was sorted as a Gryffindor when he rarely shows Gryffindor traits.
Percy Chooses His Career Over His Family
To keep a good standing in the Ministry, Percy chooses Fudge and his paranoid denial about Voldemort’s return over Harry’s truthful claims. But, not only does Percy turn against Harry, he also makes a substantial move against his parents and siblings. Not even the more utilized Slytherin characters, such as Draco Malfoy, are shown to do that. Draco’s acceptance of the Dark Mark and Voldemort’s tasks during his sixth year was due to loyalty to his parents, however misplaced it may have been, and the fear that Voldemort would kill them if he failed. Percy, whose family was on the right side of the war, could not get over himself to stand with them until the Battle of Hogwarts started.
3 Romilda Vane’s Love Potion Scheme
Romilda Vane is a very supporting character in the Harry Potter franchise, and she is not relevant at all until Harry’s sixth year. At the height of Harry’s popularity, when he is known as the Chosen One, Romilda is willing to go a little too far to get her way.
Ron Becomes the Unwilling Victim
To get Harry to be with her, Romilda Vane chooses to manipulate Harry’s feelings instead of actually trying to talk to him. But, things did not work out her way. Luckily for Harry, he never eats the love potion-infused chocolates. Unluckily for Ron, he did. Ron becomes the sufferer of Romilda’s potion, claiming to be in love with a girl he has never spoken to. Ron became a robot of the potion’s influence, which is exactly what Romilda wanted from Harry, even if the intent was not to eat so many of the chocolates at once. Romilda’s willingness to force non-consensual feelings on anyone was a drastically inappropriate step, and certainly not the best actions of a Gryffindor student.
2 Lockhart’s Obliviation Plans
Given how incompetent Gilderoy Lockhart is at absolutely everything, no one would have initially guessed that he was sorted into Ravenclaw as a student. He had to have some sort of promise, but eventually, two things got him through to a successful career: his charisma and his knowledge of obliviation charms.
Lockhart Turns His Wand on Harry and Ron
It was already bad when Lockhart had obliviated wizards, taken credit for their work, and used those stories in his books. It was worse when he tried and failed to teach students because he actually did not know anything. But, to try and take credit for saving Ginny Weasley in the Chamber of Secrets by obliviating Harry and Ron’s memories of the events and of Lockhart being a fake was just not a great decision. Not only did it backfire, but a grown man turning his wand on two children with the intent of harming them in any way was not someone showcasing that they were a great person.
1 A Ravenclaw Turned in the DA
Given how it differs from the novel to the movie, this one detail is slightly varied. However, in each iteration, a Ravenclaw student is the one who turns in Dumbledore’s Army to Umbridge. While Marietta Edgecombe turns on them in the book, it is Cho Chang who ruins the DA in the film.
They Turn Against the Importance of Learning
Ravenclaws value learning and wisdom, so turning in Dumbledore’s Army, where students are learning Defense Against The Dark Arts in preparation for their OWLS, and the brewing war outside, just does not make sense. While Umbridge is terrifying, and everyone is likely feeling and experiencing a lot as tensions are rising, showing Umbridge the truth is a betrayal to all of those who just wanted to learn magic. Harry and Cho’s romance hits a dead stop in the aftermath of Dumbledore’s Army being discovered.
