Trying to answer unanswered harry potter questions because i have a big brain 🧠

 1. In the first book, Hagrid told Harry that "There isn't one wizard who went bad who wasn't in Slytherin" but Hagrid believed that Sirius Black was a mass murderer and a big Voldemort supporter. Why?

Most people say that Hagrid probably forgot, but I don't think so. I think he was trying to make the day special for Harry (because Harry just found out he was a wizard and it was his birthday) 

and didn't want to ruin it for the boy by telling him about who Sirius Black allegedly was. Also, Hagrid might have received instructions from Dumbledore about telling Harry more than he needed to know at the time. Hagrid is way too underappreciated to be honest.


2. Why isn't Healing taught at Hogwarts?

While Healing may not be taught as a separate subject at Hogwarts, I think the students must've been taught little healing spells and charms here and there. For example in Charms, I would consider the Cheering Charms taught during the 5th year, as something which heal  because, mental health exists too, you know 😕? Also I think the students must've picked up something from Madam Pomfrey from time to time.


3. If Wizards can fix and heal so effectively, why can't they just fix eyesight?

This has been asked by LOADS of people. My take on this, is that eyesight is very delicate/fragile, and wizards probably don't have a spell for it. Even if they created a spell for it, I don't think many people would use it because eyesight is very important, and it can be easy to lose if magic is performed on them.

I stumbled upon many more questions, but I didn't include them  because

a) My brain can't think of a solution to them

b) IT WAS ALREADY ANSWERED IN THE BOOKS DON'T ASK "UNANSWERED" QUESTIONS IF YOU HAVEN'T READ THE BOOKS.
