Look at the narrative here. No one's talking about Cersei and the rest. Everyone's just talking about how Dany is the true monster of the show.
We deserved better than a building falling on jamie and cersie
Agreed. Cersei deserved a slower, crueler death after all the shit she’s pulled. The real reason for the slaughter at Kings Landing though is that Cersei killed Grey Worm’s woman. He promised to storm the City and kill everyone in it before he had to watch that huge muhfuhkah chop her head off. And, he wasn’t giving a fuck about no bells. Also, remember that Bronn is still out there though I can’t imagine even he would pursue a contract that he’s only been paid halfway on.
