^^ I'm not sure how people can still view him as the hero. The whole point of the show is that Walt becomes an irredeemable asshole.
He's an antihero.
In fiction, an antihero[1] (sometimes antiheroine as the feminine) is generally considered to be a protagonist whose personality can be perceived as being villainous and heroic at the same time, in contrast to the more perpetually noble characteristics of an archetypal hero or the perpetually immoral characteristics of an archetypal villain.
Unlike traditional heroes, antiheroes are not as fabulous as the traditional ones. They may be corrupt, oppressive, etc., or may merely have no unusual qualities whatsoever (the common definition). They are not villains but not necessarily heroes. They may do bad things but are not evil. They may fight villains, but not for the reason of justice, or if it is for the cause of justice will take an "ends justify the means" stance. Their actions are motivated by their own personal desires, such as revenge. For example, an antihero may steal, vandalize, and perform other "bad" acts but may do so for a good cause or even an unexamined motivation.
Yes he's doing bad shit, but he was always doing it as a dude who is dying from cancer who wanted to give his kids a better life. People can relate to that.
Of course now it's starting to change a bit, because in doing so he's pushed away the very thing he was trying to protect.. So wouldn't surprise me if we now gradually start to associate with Walt less and less, to the extent we fully support his opponent(s).
I keep waiting for the moment Walt goes absolutely batshit crazy and starts his own gang running the meth distribution, with him at the top.
Ended up pretty much there.
His 52nd birthday is presumably when he dies, i.e. the clips we saw at the beginning of series 5.. Although we're not going to see that until next summer. Certainly I can't see a year passing by the end of this series (2 episodes away..).
Looks like he's going out in a blaze of glory anyway, and who knows who it'll be against. We've just had some new "big guys" introduced to the scene.
There's also Mike and Jesse. Jesse doesn't have it in him to successfully take Walt out I don't think.. Skylar I don't think can die, so far as she's the one protecting the kids and such - not entirely sure where that's going. There could be a suicide I guess.
I think Hank will discover Walt too, although it may be after he's dead. Alternatively, it's just as likely that Walt ends up having to kill Hank. Walt's not exactly his biggest fan, and that's been highlighted on numerous occasions with the tone of voice Walt uses with him.
Maybe Walt ends up having lost/killed everyone around him, and then the whole thing ends with him getting his comeuppance in the big arms battle at the end? Maybe that's even against the police as a final stand?
He certainly won't die from the cancer, although at some point that's going to start making a return I expect.
Whatever it is there'll be a happy ending, cas it's American, and American audiences don't like anything without a happy ending.
I'm pissed off that I have to wait until the end of next summer to see how it all pans out though. Re-watching series 1-4 atm, too. Pick up on so many subtle things I missed first time round.
