Cersie’s the new Queen of the Realm and has now gone mad over the loss of her children. She burnt the Tyrels, The Faith and everyone else. After her son’s suicide, she even asked to burn his body. This obsession with burning down everything draws resemblance with the Mad King. And everyone knows that Jaime had stabbed the Mad King.
What if he has to stab her too in order to maintain peace in the realm? That would be the ultimate ending to this love story that would bring Game of Thrones the same charm as Shakespeare. When you have to take harsh decisions for the right causes. Sobs.
