Best band name EVER.
As for good and bad families....no. It's not that there's no straight up GOOD or BAD families...you are kicking the football at a goalpost that doesn't exist. There's no fucking GOOD or BAD.
The people with the most noble intentions(Ned, Stannis, Dany) are sentencing so many people to death it's ridiculous. They're "good", and if you are following the story at all you realize that means fucking NOTHING.
Just...just get the fuck over the idea of good and bad. You root for who you like, you root against who your don't like. Get over the idea that someone is right or wrong, good or bad. No one in the story views themselves as the bad guy. There's no lurking darkness driving people to commit evil acts.
The Lannisters aren't evil. The Greyjoys aren't evil. The Targaryen's aren't evil. NO ONE is evil. There is no evil. The Lannisters, Targs, and Greyjoy's aren't even necessarily WRONG. They all work for the betterment of their families, but none of them are doing it out of some evil desire to subjugate the world.
Even the "evil" characters like the Mountain aren't evil in the traditional sense, they're just fucked up horrible people. They're not driven by some power greater than themselves. They are occasionally enabled by more powerful people, but even then their awful acts are "justified" as a means to an end that is the "rightful" path for the kingdom.
I maybe shouldn't have had that last beer...but the point I'm getting at is that the deeper we get in to the series the more obvious it becomes that no one is good or bad. People just are what they are. Sometimes those people have power by birth....that sucks.
