Breaking Bad is a story about ressentiment; about a man who feels himself marginalized and neglected, powerless and ineffectual, who, therefore, cannot resist the temptation to establish himself as a Power — as a man who says, and means it: “I am the one who knocks.”
Better Call Saul dramatizes a radically different form of human frailty: the temptation of the con. The person so tempted may be socially marginal or socially dominant or something in between — though the marginal will have a few more incentives pushing them towards scamming. What’s at work here is not ressentiment but rather (a) a desire to dominate people, a desire to know what they don’t know and act on that knowledge in a way that enables you to triumph over them, and (a) the intellectual challenge of building a successful scam: the meticulous planning, the anticipation of the responses of your marks, the ability to improvise when things go wrong. What you see in Better Call Saul is, first, how the power of these two motives — the desire to dominate and the love of intellectual challenge — vary from person to person, and within a person from moment to moment; and also the crack-like addictiveness that follows upon the running of a successful scam.
Both shows then are about extremes of human frailty — frailty become perversity, perversity become wickedness — and how inescapable the associated habits of thought and action can be.
