Little Finger & Sansa: Stockholm Syndrome?

Fanfic authors here typically write Sansa as Catelyn reborn, while missing that in a lot of ways one could argue she's got a whole heck of a lot of Ned in her personality--probably moreso than her mother. Sure, Sansa has adopted the social pressures of the South that Catelyn has instilled in her, but at the same time there's a lot of Ned in her that especially comes to light in the later books.

Yup, I find amusing how everyone delights at the prospect of Petyr effectively "corrupting" Sansa into a Machiavellian femme fatale. Thats cheapening the inner growth of one of the most morally strong characters in the whole series. I don't know why they see Arya as the most morally good of the two sisters when she is alongside Catelyn the only "living" Stark near the gray moral zone and rush to label Sansa as a naive turned cynical and disloyal when she isn't really naive. She is an idealist and compassionate, like Ned.

That "life isn't like in songs" quote she is constantly told bears a lot of truth, but the ones who say that (Cersei, Petyr and Sandor) aren't exactly the most adequate persons to give Sansa lessons about reality, considering that the three of them are quite delusional when it suits their personal motives; especially Cersei, Sandor is quite less delusional. But ey, they're right. Being kind and generous is a ludicrous thought, trying to shoehorn the daughter of your childhood friend into your imaginary concept of a lover just because she has her same hair colour, however, isn't being self-deluded. Right, Petyr?

I always thought that one revealing point in the dynamic was that Petyr always lusted for Sansa, seeing her as a surrogate for her mother, just because she is a lady and has the same eye and hair colours while completely ignoring the younger daughter who's more akin to her cause he sees her as another Ned. This for me has always been the big hint which proves the truth of that "littlefinger loves littlefinger" quote, that his obsession over Catelyn was merely self centerd, thats it; to satiate his ego, he wanted her cause she was beautiful and out of his reach. For starters, if he really loved Catelyn he wouldn't lust after one of her daughters and spread rumours about her, but if he really knew Catelyn, he wouldn't agitate things like he does in the books.

It is not only poetic justice that he is going to fall because of Sansa, it's poetic because he is going to fall because he is going to discover that he's been trying to corrupt and deceive a girl that deep down is like the man he despised and betrayed, all the while showing all of his cards to her.
