10 Biggest Mistakes That Led To Game Of Thrones Deaths
3. Freeing Jaime Lannister - Catelyn & Robb Stark (And A Number Of Their Supporters)
The Mistake
There were a number of mistakes on the path to the Red Wedding. In Season 3, Robb decides that, with all other options spent, he must once more ask the Frey army for their help, this time to allign with him in his efforts to take Casterly Rock, leading to a new marriage pact that culminates with the Red Wedding. If he hadn't trusted the Freys, it wouldn't have happened. But he only needed the Freys because he lost the Karstarks, something that happened after executing Rickard, which itself came from ignoring his mother's counsel, but also losing support over marrying Talisa. Marrying Talisa was also a mistake, and again he ignored his mother's counsel on that, because she had freed Jaime Lannister. While Catelyn's intentions were understandable in freeing the Kingslayer, it destroyed the trust between her and Robb, leading to bad decision after bad decision.
The Death
Do we really need to go through this again? Doors close, the music shifts, the blood flows, and the Lannisters send their regards.
