To paraphrase the great philosopher George Thorogood, the final eight participants in TVLine’s March BADness Bracket Tournament are b-b-b-b-bad to the bone.

And yet still, only one of them can be b-b-b-b-baddest.

That’s the way it goes when you’re dealing with monsters, madmen and maleficent mamas: They simply won’t rest ’til their rivals are snuggled up under dirt blankets — or they wind up six feet under themselves.

For the next few days, we’ll be asking you to winnow down the field to one ultimate villain. So find a seat in our online Thunderdome, head down to our polls to vote for your favorites (Voting for these Round 3 matchups will be open for 18 hours), then hit the comments to justify your picks.

Our latest matchups include the titular villains of Dexter and Bates Motel — Dexter Morgan and Norman Bates — plus a second bout between Victoria Grayson from Revenge and J.R Ewing of Dallas.
