Mine would be Tim Roth in the Liam Neeson film Rob Roy. As Archie the fey murderous ward (probably son) of the Duke of Montrose he was his sworn enemy. After causing a poor servant girl's pregnancy (she hanged herself when she was cast from the household) he raped Rob Roy's wife, razed their dwelling to the ground and pillaged the surrounding countryside.
Favourite lines: Duke of Argyll: What heinous crime caused you to be exiled to the Carolinas? Drink, the cards, by the looks of you sir young boys perhaps?"
Archie: ( sneering) Last time I buggered a boy sir I was unaware of it until the point of entry.
Duke's henchman "Typical Englishman. Cannae tell arse from quim"
At the finale Archie gets his after a memorable sword fight with Neeson.
