By my estimation, about 75.3% of internet capacity is currently being taken up by articles about Breaking Bad (yeah, science bitch), but I'm pretty sure is the first person to compare Walter White with Batman.
The gist of Lindelof's well-argued piece for Vulture is that Walter White/Heisenberg shares more in common with the Dark Knight than you might expect and that the two iconic characters were created by a chemical reaction.
Here's a section of the article for you to check out:
The conventional thinking is that Bruce Wayne became Batman on the day that his parents were murdered. This is his origin story. We all know it. We all accept it. We all love it. Because it makes sense. Your parents are gunned down in front of you, so of course you vow an unending vendetta against crime and then dress up like a winged mammal to exact it. Except that’s not how Bruce Wayne became Batman. Bruce Wayne was already Batman. Because millions upon millions of people are murdered by criminals all the time — especially in comic books. But the sons and daughters of those people do not become Batman. But Bruce Wayne? Bruce was different. There was something inside him. Lying dormant. He just needed something powerful enough to awaken it. In chemical terms, this is called a catalyst. In the very first episode of this masterful show, Walter White is told he has advanced, inoperable, most likely fatal lung cancer. And in that moment, time slows down. Sound drops out. It is intense and it is effective and the reason we are starting here is because this is the start. The origin. The moment Walt begins his journey. The moment he becomes Heisenberg. We know all this because Walt tells us so. The ticking time bomb that is the cancer becomes his rationale for everything that comes next; the lying, the lawbreaking, the child-poisoning. But then the cancer goes away. This is the equivalent of Bruce Wayne’s parents suddenly reappearing to him and saying, “We had to fake our deaths when you were a kid and we’ve been in witness protection all this time, and we’re so sorry, but the guy who shot us was actually an FBI agent helping us and he wasn’t even a criminal and we love you, so can we have our pearls back and NOW YOU DON’T HAVE TO BE BATMAN ANYMORE!!!” But would Bruce stop being Batman? No. He would not. Because he is Batman. And once the catalyst has … well, catalyzed? There is no going back. And this is how I know the same is true with Walter White.
I suppose it comes down to the whole "nature vs nurture" debate. Are heroes and villains a product of their surroundings or are they born with greatness inside them and just need a catalyst to realize their potential?
