I went over Cersei Lannister’s selfish choice of not aiding the Starks and Targaryens against the White Walkers at the end of Season 7 and I think I have a full analysis of her current mindset. She was raised on the basis of the so-called “game of thrones” that the nobility of Westeros was obssessed about. Because of that, the “game of thrones” is all she knows or cares about. Without it, she’s nothing and the Iron Throne she has coveted her whole life is just a useless piece of scrap metal. Therefore, when she realizes that the world was ending she was desperately clinging onto the reality she once knew. The corrupt world she relished was about to cease to exist with its treacherous denizens joining the giants and children of the forest in extinction. As Morgan Freeman once said in the Shawshank Redemption, Cersei has been institutionalized and she cannot accept a any other world except one where everyone is at one another’s throats. She also may be experiencing what most people experience when they witness the end of the world, doing whatever they want because nothing else matters. In Cersei’s case, she wants to keep betraying, murdering, and extorting everyone around her until she dies with the rest of the world. Aegon “Jon Snow” Targaryen and Daenerys Targaryen thought showing Cersei the Wight would convince her into joining them against the White Walkers, but all it did was push her even deeper into insanity. Now she is becoming more paranoid and seeing treason around every corner like the Mad King did late in his reign. I would not be surprised if Cersei finishes what the Mad King started and blows up the rest of King’s Landing with wildfire. She already blew up the Great Sept of Baelor so I think she is definitely capable of destroying the rest of King’s Landing as well. Like the Mad King, Cersei will think “If I can’t have the Iron Throne then no one will!”
Just as Jaime warned her, this final treachery is going to come back and bite her hard in the ass. “And when the fighting is done, someone wins. You understand that? If the dead win, they march south and kill us all. If the living win and we’ve betrayed them, THEY MARCH SOUTH AND KILL US ALL!!!” When the White Walkers are defeated and even one of Daenerys’s dragons survives, then Cersei and her sycophants are doomed! Cersei always blamed Tyrion for the destruction of House Lannister’s future, but it has always been her and by the end of the new Long Night, the name “Lannister” will no longer be a name to be feared like Tywin wanted. Instead, the name “Lannister” will become a synonym for treachery and dishonor and it will be all Cersei’ fault. I can’t wait for Cersei to meet her fate as the final round of the “game of thrones” is completed.
