The actions in question often relate to the downward spiral of the show’s anti-hero, Walter White, who after a cancer diagnosis, goes from ordinary high school chemistry teacher to brilliant and violent meth kingpin. While overtly a modern Western about science, drugs, and criminality, Breaking Bad is secretly a moral treatise.
Widely touted as one of the best television series of all time, Breaking Bad concluded in September 2013. The show has also been criticized for its grittiness, cynicism and lack of humanity. There may be certain times when viewers will inevitably feel cynical because the show accurately portrays human failings, consequences and the tendency for self deceit. All moral choices are human, but some are just not pro-humanity. The show's deeper purpose is to realistically explore overarching themes of moral choice, personal conduct, responsibility, self-deception, and karma.
