|Annnnnd - That's a Wrap|
It's interesting that such a dark series had such a 'happy' ending, at least in Breaking Bad terms. There was no fixing the damage Walt had caused, or regaining the love of his family. Hank was dead, his son and wife hated him, Jesse was gone, and Todd was running the meth business as only a good-natured psychopath could. But there were things Walt could do, a short term bucket list if you will, things that would settle matters and tie up loose ends for him. The choices that remained for him were to act against the people who represented a threat to his family, the ones who had killed Hank, taken Jesse and brought about Walt's complete debasement. THEY were the remains of Walt's to do list in which the last item was 'lay down and die'.
Terrorizing the Schwartzes into laundering the White family fortune was a perfect example of Walt's combination of brilliance and brutality. In checking the first box on the bucket list, he corrupts them, making them in some way complicit in his crimes in a way they can never quite escape. Walt knows that as time goes by his plan will become their plan, and accomplishing it will be a kind of success.
Item number two was that pesky ricin. It's been in play for years, and now it comes out. A brief five minute meeting with Lydia in a coffee shop, followed a day later by a triumphant phone call to let her know that even though she's not dead yet, he had murdered her. Brutal, as the final admission to Skyler: "I did it for me" was brutal honesty.
Then, in an almost cartoonish climax, the old machine gun in the trunk trick wiped out Jack, Todd and the Nazis. But it had to be - Jack shot Hank in front of Walt, and Walt was never going to let that stand, no matter how weak and helpless he appeared to be in that cabin in New Hampshire. But it was key to the actual denouement - the final confrontation with Jesse. And when Walt implores Jesse to shoot him, and Jesse tosses him the gun saying "do it yourself", we are witnessing the true end of Breaking Bad. Jesse walks out, free and something approximating whole, and it remains only for Walt to lay down next to the meth lab he built and die.
