Is Skyler complicit? Is Walt driven by greed? Is Walt really a bad person? Was all this inside him all along?
Who cares? Who cares, who cares, who cares? I'm not saying who cares about the show — I'm saying this is becoming the point of the show. What makes Breaking Bad one of the most moral shows in the history of television is that actions have consequences, whether those actions arise from pain or greed or fear or panic. You pay for your actions, not the operation of your heart. The psychoanalytical journey we could all choose to take — and that most of us have taken — with Walt is a bloodless exercise. It is a luxury afforded to people who can see selfishness and wickedness and violence in the abstract, the way you can when it's on television.
What these final episodes are doing is showing no mercy, because evil shows no mercy. That's not "Evil Shows No Mercy" in a tattoo-it-on-your-arm kind of way; that's reality. That's the reality of the fact that the reason to be a moral person is, in part, that brutal acts of violence do not take place inside a cage where the only ones hurt are the ones who deserve it — rats, or finks, or phonies, or fools. When you embrace doing whatever you want in order to get what you want, you cannot isolate the consequences. This is not a show that will ever be revealed to take place inside a snow globe; it's a show where everything spills everywhere.
Walt is as bad as bad gets. He is a sucking, mile-wide whirlpool that sinks aircraft carriers like Gus Fring, and working-stiff boats like Crazy 8, and reckless idiots on speedboats like Jesse Pinkman, and flawed, leaky sailboats like his wife, and Coast Guard patrol boats like Hank, and ultimately his own kids, out for a swim.
