I would say that this story represents just why Dukat is such a compelling character. He can go from Perfect, Guerrilla, leader of the Union to Madman and still steal the show. AU Dukat is a man with the same pride, Intelligence and sense of duty that we see in all Cardassians(with the obvious exception of the traitor Broca
) the difference is that he is now the victim rather than the oppressor which makes for an interesting dynamic.
I still cannot see the Cardassians as the conquered subjects, it seems to go against the existing order somewhat
(I must admit that i always root for the Cardies,especially after the Klingon's attacked them!)
