Although there are plenty of violent criminals to choose from in Fargo, some characters have stood out across the show's five seasons as the most dangerous of all. Fargo plays on the relationship between good and evil, and the evils can be extremely dark and utterly devoid of redeeming characteristics. Each season of Fargo brings a new cast of hired assassins, crime lords, serial killers, and other deadly characters. The best seasons of Fargo usually have the best villains, and the show has created a wide variety of compelling killers over the years.
