Walt’s last noble moment?
Some might say it’s when he leaves the baby in the fire station and calls Skyler with a fake rant about how he made her do everything, to try to get her off the hook. Or maybe even the finale, when he arranges for his son to get his money. I can see that perspective, but I have a hard time calling anything he did “noble” by that point in the series, because he had also sexually terrorized Skyler.
Others might similarly argue that nothing he did after killing Jane (and he did kill her: he didn’t just “let her die”, because he overcame her careful preparation of lying on her side by violently shaking Jesse and knocking her on her back, then not intervening when she started choking on her vomit) can be considered noble or redeeming, especially since that also led to two planeloads of people dying.
But I would nominate a moment in between: the beginning of episode 4.12, when Skyler is going to Hank and Marie’s to join them in being protected by the DEA and Walt refuses to go along. He had intended to protect the whole family by having them relocated by the vacuum repair guy (later, we learned, played by Robert Forster). But Skyler had given the money to Beneke to pay back the IRS, so there was not enough.
Instead of raging against Skyler for having doomed them by giving his money to the guy she slept with (and cruelly threw in Walt’s face “I.F.T.”), he told her that it was all his fault, they would never be safe as long as he was there, and he should be the one to bear the brunt.
Would you pick one of the other inflection points I mentioned, or a different point altogether? I suppose you could go way back to when he refused to take his ex-partner’s offer to pay for his medical care (and maybe implictly, to take care of Skyler and his kids after he died).
