Who is the stupidest character in Game of Thrones?
That's a good point. But what about Bran Stark? He climbed a tower and saw something he wasn't supposed to see, which led to his fall and paralysis.
Yes, Bran's actions were foolish, but I would argue that Joffrey's impact on others was much greater. He was directly responsible for the deaths of many innocent people.
