How to evaluate Petyr Littlefinger in American TV series Game of Thrones? Baelish?

What Lord Berthier and Lord Frank have in common is to start from a small diaosi, try not to get their hands dirty, kill their immediate competitors, and finally reach the peak of power. How to consume and kill opponents quickly, efficiently and without self-destruction? Of course, the best way is to provoke opponents to kill each other. Littlefinger is an expert in this field. Why do you do this? Let's start with Littlefinger's background and experience. Born in Finger Peninsula, it is almost the lowest and poorest area in the seven kingdoms.

Petyr baelish's great-grandfather was a warrior swordsman employed by the Cobray family, so when his son became an sworn knight, he chose Titan's head as the family badge. Lord Baelish's father is the smallest of many small lords, and only the smallest one in Finger Peninsula owns some rocky land. In the battle of the Nine Copper Kings, his father forged a friendship with the Tully family, so Petyr was sent to Riverrun as an adopted son. Riverrun was always happy when he was a teenager. There were two older sisters, Caitlin and Lysa, and an idiot named Edmund. His nickname "Littlefinger" was also given to him by three brothers and sisters Tally.

At first, Littlefinger didn't feel any different from the Tully family who guarded the river. He thinks he can marry Caitlin from childhood. It was not until Duke Tully announced that Caitlin would be engaged to brandon stark, the eldest son of the Northern Guardian, that Littlefinger found it almost impossible to climb the tall branch. Angry Littlefinger chose to fight Brandon, and Brandon easily defeated him and humiliated him. Finally Caitlin stepped in and gave up. Since then, Caitlin has cut off any contact with Littlefinger. Lost Littlefinger was drunk and happened to sneak into his bedroom with his second sister Lysa, who had a crush on him. Littlefinger took Lysa as Caitlin and had sex with her. Lysa soon became pregnant with Littlefinger's baby. It is revealed that Duke Tully drove Littlefinger out of Riverrun and knocked out Lysa's baby with moon tea, which led to the decline of Lysa's fertility.
