@M.A.R. in the TV show the Hound initially kidnaps her in order to sell her, but he ends up mainly protecting her and kind of liking her. So in the books, who she kills? Why is it darker? In the show she does not kill innocent people, except maybe one as the final Faceless test. (Some theater lady, still didn't re-watch that episode in season 6)

@M.A.R. oh... interesting that in the TV show they keep her good. Actually, in the show all Stark are good without a trace of evil.

Let's jump back a bit, in the books does Cersei kill the Sparrows and the Tyrells? Does Tomen commit suicide as well?

Thanks Mr. Spoiler

Cersei gives the sparrows some power, but then since the high sparrow is not a puppet he makes her walk the walk of shame. Killing them will probably happen in the next book. She did kill the last high sparrow though

The last thing that happens in Book five (in epilogue) is Kevan dying by a crossbow to the belly by Varys

Cersei being the paranoid bitch that she is, is of course going to blame Tyrion and the Tyrells. It very much might happen, killing the Tyrells

Arya is a very morally dubious character. It's definitely a downgrade for her

Her first kill is a stableboy who has probably realized she is Arya Stark. This is happening when all Ned's men are being killed

After that, she goes through a lot. An awful lot. She ends up with Yoren, and the war has broken out so what they see in the road is Tywin's men sacking and murdering and butchering

Amory Lorch attacks a small stronghold they were staying in for the night, she kills someone there too IIRC. Then she and three boys manage to escape

Only to be caught by Gregor's men

She's thrown into a cage with other villagers, everyday witnessing torture and death.

She's taken into Harrenhal, serves a couple of masters, gives Jaqen three names to kill, the third name being Jaqen. So he buys his life back by getting Rorge and Biter, killing all Lorch's prison guards with the help of her death soup, releases some prisoner northmen who kill other Lorch men and Bolton enters Harrenhal. She then escapes with Hot Pie and Gendry, on her way out killing a northman that guarded some side door

. . . Her hands are very much dirty.

There are a few other kills later on, not all of them deserved. She connects with Nymeria's skin at night, leads a huge pack of wolves, and tastes man blood o.o
