How do you mean "cosmic alignment"? If you mean comeuppance or karma, then that'll be coming up next season I'd imagine. Walt did what he did and it's not out of character. The show is called Breaking Bad, it's no surprise that Walt is increasingly becoming a monster (I was chuffed by Zarathustra's description of what is essentially Walt losing all morality as reclaiming his Ni vision and becoming a proper INTJ a few posts ago, by the way).
That.
There's Te and there's Ni. As Walt leans more heavily on procedure, he moves further from vision. Knowing that he is one who would sacrifice children and yet saying that Gus is the one, he's acting out a plan. Not envisioning.
Way back when Jane was choking her last, Walt wasn't acting out a plan. He was trying to but lots of things were a bit out of his reach. Not a lot. Just a bit. And, naturally he was a prick about it and focused it all on Jesse. And then something falls into his lap: Jane is choking. You can see him SEEING.
Now, fair enough, if Walt's made a plan, fine, act it out. If it's a nasty plan that makes Jesse a pawn, fine. But where's the moment that he SEES he has to do this? If Walt's an INTJ, then his principal identity is happening in a closet somewhere off stage and we get to watch only the rest of the show.
But each season, Walt has gone darker and darker to fulfill increasingly selfish needs (his family is falling farther and farther from his view, he's almost purposely avoided them this season). He allows Jane to die even though it could, and does, hurt many people including Jesse. Then he orchestrates the murder of Gale, who is not directly guilty of any offense against Walt or Jesse, in a scheme that again throws Jesse off the deep end, at least for a while. Why isn't the next step risking the lives of children and sending old women into houses full of armed goons, again while causing strife but securing the loyalty of Jesse, who is the best pawn you could ask for? And I even doubt this is the bottom of the barrel morally for Walt.
Well, the cartel's in disarray, the lab's burnt, Gus is dead, and Mike probably didn't love Gus enough to seek revenge. Walt's cleared the decks.
There's still Skyler though. And Hank. WHEN--not if, when--Skyler starts turning Walt's "win" on its head.....
Boiled down, alongside excellent tension, this show is a series of moral lines in the sand and a once completely ordinary man (from a moral standpoint) crossing one, and then another and then another. The real question is if there will be a line he won't cross next year, or if he'll redeem himself in any way or go out being as bad as, or worse than, people like Gus or Tuco.
Yeah actually, will he redeem or will he get worse?
To be INTJ, he has to get worse.
ETA: as far as the show's setup is concerned, THE most outrageous, unforgivable thing Walt could set himself to do would be the murder of Junior. Why would he ever have reason to, I don't know. But currently it is THE most transgressive thing available to the show. The only untouched, largely innocent, essentially pure character on the show is Junior. But would they dare? If Walt gets caught as a meth cook, being in prison is just another challenge. But if Walt has to kill Junior...
He'd do Skyler first though.
