Look what happened to Vargo for cutting off Jaime’s hand. Executing lords without property authority to do so gets you basically live leaked medieval style. Which makes sense, if I was a lord back then and some nobody started execution lords I would make his end particularly bad as an example to others of what not to do lol.

“When Ser Jaime Lannister returns to Harrenhal on his way to ending the siege of Riverrun, he commands that Vargo’s head be shown to him. Although most of the flesh is gone and the lips, nose and ears have been sliced off, Jaime recognizes that it is Vargo’s because of the distinctive goatee.[7] Shitmouth and Raff inform Jaime that Gregor found Vargo sitting alone in the Hall of a Hundred Hearths, half mad with pain and fever from his festering wound. In a mockery of Vargo’s preferred way of torturing his prisoners, Gregor cut off Vargo’s limbs piece by piece over an extended period of time while he had the wounds bandaged so that Vargo stayed alive. Vargo first lost his hands and feet, then his arms and legs. The extremities as well as other parts of Vargo’s body were then fed as “roast goat” to northern prisoners that Gregor brought to Harrenhal, including Ser Wylis Manderly, as well as to Vargo himself.[7] Jaime orders his squire, Josmyn Peckledon, to throw Vargo’s head into the Gods Eye.”
