We're running out of wolves (just like we're running out of Starks, I guess). Those deaths always hit me as hard or harder than the rest.
I am not sure if the Stark deaths or the wolf deaths hit you the hardest. The Stark deaths should hit me harder, but there is always a "boy did he have it coming" aspect to it when a Stark bites the dust. Let's go down the list.
Ned - pokes the hornet's nest over and over while standing right underneath it. Shows a little bit of brains and gets Robert to sign on to someone other than Joffrey as heir, than chokes when Renly (and by extension Loras) offers his army to seize power.
Robb - Yes, his wife was hot, but boy was that stupid. When someone hands you a kingdom if you will marry his granddaughter, you marry the granddaughter. I have a daughter, and I kinda see Walder's side of the story on the Red Wedding.
Katlyn - She pretty much made very wrong decision possible, every step of the way. She got played by her sister, kidnapped, then lost, the Imp. Couldn't keep Stannis and Renly from fighting, and then didn't tip her son off that Walder and Bolton were snakes. The only reason that Sansa, Arya, Bran and Rickon are still alive is that they were far away from their mother.
Jon Snow - got killed once already for not appreciating just how pissed off some people were about his decisions. The decisions don't seem to be getting any better.
Sansa - gave up her dad to the Lannisters. Now appears to be in the process of leading Jon Snow into a beatdown against Ramsey despite the fact that Baelish is offering an army that would destroy Ramsey's. Even Brienne is having second thoughts about her oath because she realizes just how f#$%ing stupid Sansa really is.
Arya - she is hanging out with some seriously shady characters, is lying to them, and clearly isn't doing a very good job of it because they keep threatening to kill her if she doesn't stop lying.
Bran - After being told that the White Walker's assault is imminent, decides to watch the "oldies channel" with the 3 eyed Raven instead of fleeing immediate. He has gotten Hodor and Jojen killed, and is getting dragged around the snow by a 5'1, maybe 100-110 pound girl while an army of undead is probably only about 100-150 yards behind him.
Rickon - got himself captured by Ramsey. This was kind of not his fault, but given how stupid his parents and siblings are, he probably did something to cause this.
