4. Joffrey Baratheon, 'Game of Thrones'
Seven gods, seven kingdoms, zero redeeming qualities — the atrocious boy king who bedeviled House Stark was a living embodiment of George R.R. Martin's furious fantasy revisionism: If you're a rich man with a good family name, you can get away with literally anything. In Joffrey's case, this included torture, murder, sexual assault, the beheading of the show's main character (R.I.P. Ned, you were too good for this world), and generally being a sneering little shit. He was so hateful that the few times he received any kind of comeuppance—an insult, a slap, a good old-fashioned regicide at the so-called Purple Wedding — are among the show's most meme-able moments. Actor Jack Gleeson retired from showbiz immediately upon completion of the role; by scraping the bottom, he went out on top.
