If you’re a fan of Harry Potter, then it’s likely you’ve thought about what house you’d want to be sorted into. Those who value their intelligence tend to favor Ravenclaw, while those who are courageous opt for Gryffindor. The cunning Potter fans out there imagine themselves as Slytherins, with most people generally avoiding Hufflepuff altogether. Although each house has its merits, they don’t always define the people sorted into them. Many of the franchise’s villains might have stemmed from Slytherin, but that doesn’t mean every one of its characters was destined for evil.
Considering what we saw of Horace Slughorn in The Half-Blood Prince, it’s hard to believe the man was once a Slytherin. Sure, his intentions weren’t always the best, particularly regarding his lust for money. However, a desire to make a few extra bucks doesn’t make someone evil. Even if the potions teacher was responsible for teaching Tom Riddle about Horcruxes, he didn’t do so with malicious intentions.
Most of what we saw of Slughorn showed him to be a compassionate and fun-loving person, albeit a bumbling fool at times. He was a teacher that was hard not to love, and the kind of role model Slytherin needed more of.
Voldemort’s followers don’t betray their master and live to tell the tale. Sadly, Regulus Black suffered a grisly fate at the hands of the dark lord, but at least he went out a hero. The man defied Voldemort when it mattered the most and stole the locket containing one of his seven Horcruxes. That was no easy feat.
Regulus might not have always done the right thing, but that doesn’t mean he was a bad person. He switched allegiances, and that’s all we care about. The character knew the risks of turning against Voldemort, but he did it anyway. We’d say that makes him a good guy.
This is perhaps one of the most misunderstood characters in the entire series. Fans believed that Severus Snape was evil from day one, and it took a while to realize that wasn’t the case. He may have been working for Voldemort and done the abhorrent act of taking Dumbledore’s life, but it was all part of a long game.
The whole time the potions teacher was making an enemy out of Harry, he was simply trying to protect him. He’d harbored feelings for the boy’s mother for decades, and we know from this series that love is far stronger than magic. After all, it was Lily’s devotion to her child that saved him from Voldemort all those years ago.
We didn’t really see much of Andromeda Tonks in the Harry Potter series, but we learned enough about her to realize she was a good Slytherin. After all, you don’t get your face burned off the Black family tapestry for no reason. It seems that Andromeda’s relatives weren’t too happy about the fact she fell in love with a muggle-born. Slytherins typically only value purebloods, so to against the grain like that was pretty controversial.
Fortunately, while her family didn’t support her actions, we sure did. Andromeda proved that you can accept others, no matter who you are. Plus, because she married Ted Tonks, we were gifted with the amazing character that was Nymphadora.
It just goes to show you can’t always a judge a book by its cover. Or, in this case, a Slytherin by their house.
