re: Game of Thrones: Who should get to kill ________? (spoilers)

Revenge and justice are often asymmetrical on GoT. The bad guys almost always get their due, but its in ways you never expected. No doubt everyone would've loved to see Robb Stark storm King's Landing and behead Joffrey, but instead Grandma Tyrell takes him out with poison. Ditto Tywin (who wasn't quite a villain, but definitely not a hero) - he doesn't die in some dramatic battle scene at the hands of a hero; he's killed on the shitter by Tyrion (another "anti-hero"). Even Locke had his neck snapped by Hodor, when most viewers probably expected an epic showdown with Jon Snow.

There is one character that's an exception to this rule of asymmetrical vengeance - Arya Stark. Arya killed the Frey lackeys who desecrated the bodies of Robb and Catelyn Stark. Ditto the thug who killed her buddy in season 2 ("that's a fine blade...."). I suppose she also achieved a measure of vengeance with The Hound. What's Arya doing now? She's becoming a member of the Faceless Men, the most-skilled organization of assassins in the world. So, if there was ever anyone who would get a really awesome moment (or moments) of vengeance, my guess is it would belong to Arya.
