Don’t you dare say he was bad in deathly hallows part 1, because it was the charm thing that was making him rude
But technically, Harry wore it too and it didn't make him say horrible things
Because he hardly wore it
Harry wore it a lot, but Ron was also grouchy from getting splinched.
If I remember correctly he did start to become rude but hermionie told him to take it off
What do you think?
