But Frey should burn in hell. Not for killing Robb, for breaking guest right and so killing 8000 years of tradition.

All the Frey hatred is unnecesary however. 75% of the Freys are very nice people and/or completely innocent.

The only nice Freys we see are Olyvar, Roslin and Ser Stevron. All the others seem to be the least-nice persons in the series. Not counting Joffrey and Cersei, that is. I mean, Walder sr. is a man who just feeds of grudges and imagined slights, Hosteen is a hot-headed idiot, Aenys an arrogant [word deleted], the same goes for Rhaegar, the one Uncat hanged was a drunk and an idiot, Amerei is a whore, Ryman an incompetent, overly self-assured fool, etc., etc., etc.

I stand with my point, the Freys must die. In fact, Robb should just have laid siege to the Twins (with Bolton's army on the other side), they couldn't have lasted long that way.

What you said about a couple of those is a little exaggerated. We haven't actually met most of them. Roose and Ramsay Bolton are more evil than they are, as is Grgfor Clegane, Joffrey, Cersei, Euron Greyjoy,Qyburn etc. Of course, I don't like most of the Freys anyway. Walder is the only one of the not so nice ones I like, and I cannot abide people's overly zealous Frey hatred. I do like Roose and Tywin, and Walder as characters, but I don't like the rest of the villains. (I don't count Varys as one)

Of course, Ramsay, Cersei and Joffrey, Qyburn and Gregor are far worse. I never said they shouldn't die slowly and painfully or fully deserved what they got.

Roose and Tywin aren't evil IMO. Just machiavellian power politicians. (did I mention I like machiavellian power politicians). They don't do evil deeds for the sake of it, they do it because there's a profit in it. They are never more merciless then necessary, but also never too merciful.

Euron we don't really know anything about except from Victarion, who isn't really the most reliable source.

I think House Frey fully deserves every bit of hate they get. As I mentioned, not for backstabbing the Starks (they had that coming, and were too stupid for words to believe Walder was willing to forgive them with nothing but an apology. I still think that's quite a plot hole.), but for breaking one of the few rules of war that still were universally honoured. You just don't kill your guests. Ever. People despise the Rat Cook for doing so to a prince who had murdered his son. Compared to that, breaking a wedding pact is nothing.

Roose Bolton

the Freys

"Don't make me rue the day I raped your mother!"
- Roose Bolton to Ramsay

The reason he raped this woman, and had her husband killed too I think was because she didn't let him sleep with her on her wedding day with her husband. Then, there's the fact that his telling of his son, points more to hiding behaviour, like what he himself had done, not about stoppin. Also, he more than imples that he has practices skinning people alive.

Roose

OK, the rape was rather evil, but beyond that, there's nothing truly evil or bad he does. He's just a master politician, playing, as Lady Dustin said, a mildly diverting game with the lives of others. The Freys, on the other hand, are a nest of intrigue, murder (under guest right, no less), incest (Black Walder) and whores (Amerei). Sorry, but I don't like them, especially as they're so petty-evil, if you get what I mean. There's no higher goal behind it, just Walder Frey's injured pride and the power struggle amongst his sons/grandsons/(Oooh, naughty word)/other progeny. All the others are going somewhere with it, except Cersei.

Roose's actions prove he is actually evil regardless fo what you think, he is just clever at hiding it. His evil is ever present. It is not just a raping action that makes him evil, it is his attitued towards it. How can you say that he is less evil than the Freys? Walder is just a spoilt old man who thinks he acn dp what he likes, in fact the only Frey who is evil is Black Walder, but Rosse is one of the most evil in the series, just not the same kind of evil as Joffrey, Ramsay etc, all Amerie does is sleep with men and you think she is worse than a man who rapes women for pleasure? And Hosteen etc are just a little arragont, are they worse than a guy who, like his son flays people alive?
