If I'm being honest, he's part of the reason why Season 3 in my opinion was so damn good. He was creepy, completely detestable, inhumane but I was still rooting for him to be the victor. I can't remember if Varga died but the third season had a season finale left open for interpretation whereas Malvo sadly died a tragic death.
My favorite seasons so far: S1 > S3 > S2
Anyway, Chris Rock should do a great job with his upcoming role on Fargo as a serious character (tbf, not a fan of his comedy skits).
