Perhaps the houses are not about who you are as people, or your personality.
But whether you are okay with your inner darkness (Slytherin), or you have the idea you must be a hero even though you are a shitty person (Gryffindor), or you are okay with being a normal person for normal people can be heroes too (hufflepuff), or you are a person who wants to continue to advance themselves, to learn, to study, for you are fine with who you are but you want to improve (Ravenclaw) developing technique, intelligence, and wisdom.
If what I said above was true, what does this say about Gryffindor and Slytherin? Who is the real hero of the two houses?
