All of the houses have the potential to produce Dark Wizards, and all of their traits have the potential to be bad in certain ways. It's just because Slytherins are ambitious, so the dark wizards produced by their house are more likely to be well-known.

I understand that but jk Rowling wrote the slytherins as very bad, I don't think there was any slytherin student in the books that was portrayed in a good light, hell they were not even allowed to help in the battle of Hogwarts
