If I see a single person screaming "MAD QUEEN" once dany burns shit down I'm gonna be angry Imagine if it was sansa/arya/bran being beheaded. I'm sure jon would fuck shit up. If he had rheagal (RIP my sweet boy) he would burn shit down. 
I'm certain IF dany burns shit down (and I really fucking hope so) people will be very quick to call her mad queen.
She has every fucking reason to just fuck it all up. She has lost EVERYTHING.
