This reminds me of a fan theory on Lost where each character was 1 of the 7 deadly sins. BUT THERE WAS WAY MORE THAN 7 CHARACTERS - that created the turmoil in the fan theory. I could always figure out that Hurley was Gluttony and Sawyer was Pride. From there it got sketchy

That might not have been true for Lost but it was definitely the case for Gilligans' Island whose creator went on to state that each of the characters was to represent a sin except for Gilligan who was the devil and keeping them on the island which represented hell.

okay, would the skipper be gluttony or wrath? And amongst the rich couple, which one would be considered greed? Im guessing the other one would be pride. The hot girl would be lust. i forget the rest of the characters. 

But how about VINCE GILLIGAN'S ISLAND

Hell - ABQ

Pride - Walt

Greed - Saul (Of course Walts not in it for the money near as much as he is in it for the pride. He has bought a total of 3 sports cars, and 1 car wash, all of them leases. The rest of the spent money has gone strictly to keeping him out of prison which isnt considered a luxury of greed. Definetely extravagant, but for that kind of cash he could've definetely done better, so for this one im going with saul).

Lust - Skyler (for cheating)

Envy -  Jesse (during S3 at least). 

Wrath - Wrath = Anger, so I am going with Mike as front runner. Theres also Gus, but he used his anger a form of intimidation rather than just blind rage in its purest form.    

Gluttony - Huel 

and a few people in the show that actually managed to escape purgatory (ABQ) briefly - Jesse, Mike, and Gus who leave ABQ in Salud.

Well i just came up with a fan theory. Of course envy, and wrath aren't perfect, and walt himself has at least 5 of these himself.

I think Vince said in the 5.1 commentary that Walt's Volvo was meant to mirror Gus's. It could be true in some cases. I kind of hope not because if true, it would suggest Walt might be responsible for Sky and Jesse's deaths. If you have seen the one promo from later in S5b, Jesse has longer hair and a beard and looks a heck of a lot like Walt from the 5.1 teaser.

What about Jane? Walt let her die, correct? Well, remember how Jane talked about the painting about the door? Well take a look at this  

Walter's birthdays, may have a connection to Jane

I think the reason Walt keeps the teddy bear eyeball is because of his connection to the plane crash. If Walt would've saved Jane's life instead of letting her die, her father would've been able to do his job correctly.  So the plane crash happened because of Walt ' s decisions and actions. 

^ I meant to add that is his token for lack of a better word for Jane's death.

I found the trait he gets from Jane. In the episode "Fly", Walter is laying in bed on his back looking at the smoke detector. Then the episode goes on and he to some extent tells jessie about him being there when Jane died. This is when he really thinks about it. At the end of the episode, he is shown again in bed looking at the smoke detector. This time, however, he is laying on his side. This is due to the fact that he was going to flip her over when she threw up. This would have saved her, so he adopted it after his realization of his connection to her death.

I know it's late but I'm recently rewatching the series. I would say the whole bacon in his age thing was more of a homage to the life he ruined, trying to recapture bits of a happier time. But you could also so since he ruined his family's life after being outed as Heisenberg he symbolically killed his wife by ruing her life,the orignal and normal Skyler we've all come to know is dead, reducing her to Heisenberg's criminal empire co-conspirator wife.
