Most people are predicting that the poem read by Bryan Cranston as a voice over for a teaser commercial for the beginning of the second half of the final season of Breaking Bad means that Walter White will become very powerful and then lose everything. I think it means much more than just that for many more people than just Heisenberg.
In my opinion, the Ozymandias poem is the prediction everyone on the show becoming too proud of their works and losing everything because of it. It is not just Walt who will lose everything, it is everyone that has followed this path to destruction. They will all lose the most important things within their lives if not their actual lives in the process.
Hank is trying to take down the meth creator that he has been searching for a long time now at the expense of his career, his humanity, and who knows what else. Jesse is trying to take down Walt because of his love of children and people and will do anything to get revenge on the man that has been manipulating him this entire time. He had a chance to get out and become another person hiding under the identity of a new life but he would rather get revenge on Walt than do that. Skyler, Marie, Todd, Lydia… they all have their points of pride which they cherish too much which will cause their downfall. Of course, Walt becoming too prideful in wanting to create an empire since he was never able to create one that should have been his in the company Gray Matter will be his downfall.
I think this poem is not just to show that someone as power hungry as Walt that has lost his sense or morals to get to a place of power will lose his entire world but it is also to show that it can happen to anyone especially when they don’t even realize that what they are doing is too much.
In Moby Dick, when Starbuck tries one last time to prevent Ahab from attacking Moby Dick and yells “Moby Dick seeks thee not. It is thou, thou, that madly seekest him!” it did not stop him. I think the same thing needs to be said to almost every characters in Breaking Bad but never will be. Even if those or similar words were spoken, I do not think they would choose to get out with their lives over their strong emotional convictions to do what they feel they need to do and cause themselves ruin in the process. They will all be just as Captain Ahab on his final chase to get Moby Dick when he says “Towards thee I roll, thou all-destroying but unconquering whale; to the last I grapple with thee; from hell’s heart I stab at thee; for hate’s sake I spit my last breath at thee.”
