I say Thenardier, with Billy Flynn being a second choice. I thought about one or two others, but decided that they were too smart for him to convincingly portray.
Patrick Bateman is definitely the best one so far - both are great stand-ins for the violent, perpetually-forgiven systems of capitalism. I can't remember if or how it's quoted in the show, but the last paragraph from the book feels chillingly relevant:
"There are no more barriers to cross. All I have in common with the uncontrollable and the insane, the vicious and the evil, all the mayhem I have caused and my utter indifference toward it I have now surpassed. My pain is constant and sharp and I do not hope for a better world for anyone, in fact I want my pain to be inflicted on others. I want no one to escape, but even after admitting this there is no catharsis, my punishment continues to elude me and I gain no deeper knowledge of myself; no new knowledge can be extracted from my telling. This confession has meant nothing."
