Many of fiction's greatest villains are mirrors to the protagonists who take them down, and it is becoming increasingly obvious how much alike Walter White is to Gustavo Fring. The parallels were there from the beginning, notably in Gus' origin as a once timid man who built a criminal empire in the aftermath of a personal disaster, having seen his partner executed by Tio Salamanca. Walt got started in the meth business after being told he had cancer, but it soon became obvious his reasons for continuing, despite regularly putting in danger the family he vowed to protect, were rooted in bitterness and anger at a world which had stuck him to the bottom of its food chain.
There have been numerous landmarks throughout Breaking Bad marking the deepening stages of Walt's journey to the dark side, be it his first kill, allowing Jane to drown in her own vomit near the end of season two, going full measures in season three's incredible finale, or poisoning a child at the end of last season to claim his final victory over Gus. On each occasion, Walt had circumstances to mitigate his decisions. Now, with no visible danger posed to his life or family, we are seeing how Walt's rise to the top of the drugs world has completed his descent into absolute villainy.
