In the final episode, we see one of the indisputable heroes of the season, Lou Solverson, driving Peggy Blumquist back to their hometown, she in the back seat of the prowler while Lou delivers a monologue similar to that of Marge Gunderson's (Francis McDormand) in the movie Fargo, where she lays out the utter senselessness of killing for money. (Lou's monologue is about the lengths men will go to protect their families and the meaning of this in life.)
In the movie, the most purely evil person in that film rides in the back of the prowler silently. Lou and Peggy clearly mirror this scene, though Peggy was not silent.
Peggy answers with her own, shorter monologue that she never meant for any of this to happen, speaking of the trap women in 1979 found themselves in, that women were victims of society too.
Lou abruptly cuts her off with obvious disdain for her ideas:
People are dead, Peggy.
Clearly she committed a crime (an almost unspeakably evil hit and run that ended up costing that victim his life), but the fact that people are dead was otherwise not her fault (the Kansas City mob planned to kidnap one of the Gerhardts anyway, and war would've ensued; the Indian Hanzee Dent is responsible for most of the deaths.)
But the framing of it - Peggy in the back of the prowler on her way to jail, and Lou, the hero, cutting her off implying her blame ("You mean the victim?" and his final remark) seems to place all the carnage at Peggy's feet, which I think was short-sighted.
Was this the message the writers were intending to send? Or was it a crafty example of how men really didn't understand the limits placed on women that could drive someone like Peggy to the lunacy she displayed? Or is it something entirely different?
