Worf is probably the truest Klingon, following the honor code and traditions of Klingon culture more devotedly than any Klingon of the Empire. He was basically uncorrupted by the true nature of Klingon politics.
Worf is a very unusual type of Klingon since he was raised by humans and overcompensates by becoming what he thinks of as an ideal Klingon. "Real" Klingons must think he's a nutcase.
I don't know why, but now I have this image of Sisko et al (when they disguised themselves as Klingons) acting like Undercover Brother when he disguised himself as a nebbish office clerk.
Sisko: "What an honorable gathering!! There is much honor here! Look at my Bat'leth! Where is the Blood Wine! Kapla! Double Kapla!!"
