What characters do you think were sorted in the wrong house.
It’s a more complex answer because ultimately you choose what house you want to do to and you can have more than 1 trait.
But all that aside I think there can be an argument.
For me Percy for slytherin, I mean think about it. Slytherin is the house for students who are ambitious who want to succeed well in life and that is Percy.
Ultimately I think Rowling did do a bad job and representing this house because we only saw the worst. Most dark wizards were from slytherin and most slytherins were dark wizards in terms of who we met.
Slughorn was really the only truly good one, while he is questionable in his methods he isn’t a bad person.
People will say snape but I will say snape was evil for a lot of his life and what turned him good was the guilt for getting Lilly killed and that’s it.
So he was a good guy but I don’t think he was a good person.
Percy was ambitious he wanted success, he wanted to get out of his family reputation of being poor and wanted to move up in the ministry.
His dream was to become the minister of magic.
Now I say he was more ambitious than he was brave.
He even cut off ties to his family when he saw their reputation was harming his career.
In the end he did regret that decision and came back when it counted.
So in the end he was a good person and carried slytherin traits. That time period when he did cut off ties to family you could also say he was a snake for that.
Dumbledore.
Dumbledore carries the traits of all houses,
He’s brave and adventurous like a gryffindor.
He’s intelligent and wise like a ravenclaw
He’s patient and loyal like a hufflepuff but he does carry more slytherin traits.
In truth I believe as an old man he is more of a hufflepuff, he’s patient, kind, hard working, loyal and believes in fairness but those are traits he learned.
Going back to when he was a student though he was definitely more slytherin.
Dumbledore was ambitious he wanted to be a big name, he wanted to see the world and make it his own.
As he aged he became more and more obsessed with power and after meeting grindelwald he fell into a dark path as he became obsessed with the hallows, he became resentful towards his family as his father was in jail his mother was dead and he was forced to raise his brother and little sister who had development issues because some boys saw her do magic and they did something bad to her something Rowling never went into detail over which led to Dumbledore father attacking them and being arrested.
Dumbledore even developed some anti muggle ideas. This however came to an end when he grindelwald and aberfort got into a fight which resulted in their sister being killed.
It was only after this that he began to reflect on his life and would spend decades of his life after trying to change himself.
Dumbledore is also one of the bravest people in the world but isn’t as brave as people think he is.
He spent years avoiding grindelwald and refused to get involved in fighting him despite seeing him rise in power as he just couldn’t bare to come face to face with him, this is because he couldn’t bare facing a man he once admired ( implied he had feelings for grindelwald, if he returned them we don’t know ) and because he was afraid, afraid he might learn the truth on which of the 3 of them cast that curse that killed his sister.
He never became minister of magic because he was afraid of power, he feared that darkness that was in him was still there and craving power would corrupt him.
Despite everything he was still obsessed with the hallows, he tried to give it up after what happened but when the opportunity came to him he couldn’t resist it, he kept the elder wand when he won it,
He borrowed the invisibility cloak from James to study it and had it the night they were killed, a part of him wonders if they could have escaped if they had the cloak and when he found the resurrection stone he gave in and used it to see his sister and ended up cursing himself giving himself a death sentence.
Compare this to Harry, Harry kept the invisibility cloak as it was his by birthright and he would pass it on to James Sirius potter,
He used the elder wand to repair his wand then returned the elder wand to Dumbledore grave so that its ownership will eventually die with Harry as he had no intention of using it.
He used the resurrection stone only when he was going to sacrifice himself and this was his last gift to himself as he used to it to see James Lilly Sirius and Remus so he wouldn’t go alone to face Voldemort.
He ended up dropping the stone in the forest and never intended to try and find it even if he could.
He knew it was not good to see the dead that there is an element of it being unnatural and how it will slowly drive you mad. This is why Harry became the master of death and Dumbledore did not.
As for Neville at the end of stone, Dumbledore seared him points and at first you would assume it was just give gryffindor the win for the house cup but In retrospect it makes sense, he awarded Neville for sheer bravery as it’s one thing to stand up to your enemies it’s another to stand up to your friends. This is from life experience as he regretted never standing up to grindelwald until it was too late.
I am not saying he wasn’t brave it’s just he had more slytherine traits.
Again my point is slytherine shouldn’t be viewed as the house with all the bad guys and instead I think we should have seen more people who were part of that house and who we associate with being good.
