As a PC Hogwarts player, "jog" is the default. There is a "sprint" as well. But to WALK I have to press C and then I cam actually take in the sights and the stunning repeated lines of dialog.
Im not too knowledgeable in Harry Potter stuff but having an anvil thrown at you or being tossed around like a rag doll sounds way worse that what ever those curses do
Yup there are tons of more brutal spells, but the effect isn't what makes them unforgivable. That part is because there is no counter spell for any of the three, you either manage to dodge them, or it's game over. For everything else there is some sort of counter, technically at least
