The Fargo villain from season 3 was also great. I loved how slimy, creepy and possibly full of shit he was.

Like, he can apparently brick your computer if you search his name, but his operation is apparently formed by him and two guys.

All the villains in Fargo are great and none of them have a point. Jon Hamm's character in season 5 is completely selfish and petty and self-aggrandizing and he's a terrifying villain.
