The terrible lies of Walder Frey

With the brand-new fifth season premiere of the award-winning television series Game of Thrones set to air in less than two weeks (insert excited dancing here), I feel that I should recap the worst, most evil characters in the show's history for the fans of the show, starting with the deceitful Walder of the house Frey.
Everyone knows Walder to be an extremely fertile old man throughout the first and second seasons of Game of Thrones. Lord Frey has been married seven times by the age of 94 and has over (brace yourself) 100 descendants. He also is very widely known for his selfish, self-centered behavior. Lord Frey did not even come to the aid of one of his biggest allies, Robb Stark, in the War of the Five Kings until he was absolutely sure that Stark would win the Iron Throne, earning him the nickname "Late Lord Frey". Remember the terms of his negotiation with the King in the North? He tried to shove off as many of his offspring as possible on the Starks, insisting that Robb marry one of his daughters, Arya marry one of his sons, and another Frey be taken by Robb as a squire. You would think that if Lord Frey was so eager to give away so many of his descendants that he would stop having children by the dozens; however, he makes it quite clear when he marries a 15-year-old girl that he did so to have more children (seriously? Gross.).
However, none of these attributes have earned Lord Frey the title of one of the worst characters ever to grace the beloved series. That title is earned in the ninth episode in the third season in the most gruesome and shocking episodes of any television show ever: The Red Wedding. Now, if you are a true and avid fan of the show, that phrase is the source of your nightmares. The sight of a Frey guard stabbing pregnant Talisa Stark in the belly over and over again haunts your thoughts, causing major shuddering and perhaps a little gagging. "The Lannisters send their regards" echoes in your ears, and you wonder if you can ever trust the director of the show with your emotions again. The Red Wedding reveals to us Walder Frey's secret correspondence with the Lannisters to kill the Starks and end the war. Lord Frey is one of the worst characters in the show's history because he slaughtered hundreds of his own house guests just because Robb Stark did not marry one of his daughters, and for that, he will "burn in the seventh Hell."
