I think Lester Nygaard just retained his Husband of the Year Award.
Seriously, what he did to his wife was probably worse than what Malvo did to his missus in the lift.
Malvo's just a sociopath, but Lester, from the minute that Malvo did that, used his wife as a human shield. When they arrived back in Bemidji, he let her enter the house first, waiting back to see what happened. And the way he deliberately set her up on the chance that Malvo would be in the shop was on a level of callousness on par with Walter White. Fuck you, Lester.
The scene in the diner with Molly's dad and Malvo was superb. What they said to each other was a small fraction of what they told each other in the unsaid space. My fear in the final episode is that Lou's dad (I really should learn his name) will be savvy enough to escape/avoid Malvo, but poor Gus isn't natural police, so will meet a sticky end.
BBT telling the man and his kids about the dead bodies in that house was amazing. He really is the devil, albeit a very mischievous one.
Seriously, though, Fuck You Lester.
