Though I'm not sure what Arktoris's criteria was for best villians (memorable lines?), I think the Joker in the Dark Knight will trump all! As to the most villianous? Watch Rob Roy, don't remember the character's name, but he was played by Roth. Absolutely impossible to not want him dead by the end of the movie! Impossible. Oh, and don't watch if you are, you know, a minor, or sensitive, or like people....
