These are “Cersei people” so when they ask for mercy it falls on deaf ears.

Also, this is a warning to any other kingdom. Its like dropping a bomb on Hiroshima. The people never did anything wrong but bombs still get dropped.

When she first met Jon she asked his opinion on war strategies after they suffered a major loss. Pretty sure she wanted to go to LL and burn shit up in season 7. Jon tells her that a dragon burning up helpless people is a bad look. They end up attacking the Lannister army while it was on the move. I think she threw all that advice out the window allthese seasons and said fuck it.. this is how EYE Rule shit.
