On Slytherin being misunderstood?

I’m re-reading the books 📕 and I love Slytherin house 🏠. Everything from The common room, the dark and brooding subterranean underground to dark magic.

Only, (sadly) I don’t think the book is nuanced about the morality of being drafted into the house. Can you been interested in dark magic without being evil. Seems like its study end up lumping people into the category of evil, or ambition. ‘Ambition’ being an insinuation of ‘corruption’.

Also, as Salazar obviously has this intrinsic evil and moral underpinnings of baseless purity, why do they still keep up his name?

I know it’s a children’s book, but I’m interested to hear what people have to say on this? Doesn’t seem like JK writes to redeem the house either.
