1) Leanna - started all this trouble because she didn't break up with her boyfriend before shacking up with another guy.
2) Ned - idiot and self-righteous jerk
3) Katlyn - falls for psycho sister's stupid lie, then kidnaps, and loses, member of powerful family. Also fails to get two Baratheon brothers to stop fighting. Lets Kingslayer go, costing Robb a big chunk of his army. Finally, walks whole family and most of their friends into slaughter despite knowing Frey shouldn't be trusted. Katlyn is terrible.
4) Robb - dumps a lord's grand-daughter because she isn't hot enough and then shows up at that same lord's castle with his hotter tail. How did he think that would go.
5) Rickon - zig or zag
6) Jon Snow
7) Sansa
Most of those people are already dead. Here is the list of the living I would like Arya to kill for me ----
(1) Danny. Let's face it, she has been a drag on the whole story. Just kill her already.
(2) Night King. He's almost as awful as Danny.
(3) Cersei. No explanation necessary.
(4) Undead Gregor. He is almost as awful as Cersei.
(5) Ellaria Sand. Stupid HBO adlib. No bastard without blood is going to rule any of the Seven Kingdoms. Plus, she killed a man of peace for no reason.
(6) Robin Arryn. Nasty little bugger with no redeeming qualities.
(7) Jaime Lannisters. The Kingslayer must pay for tossing Bran from a tower.
(8) Melisandra. Killing the Princess Shereen should have been punished with deatb.
