Novels...not to my knowledge--but sometimes, it depends on one's definition of "right". Still, I agree--for all the talk about the DS9 writers intending
them to force fans to do some soul-searching, a la "In The Pale Moonlight"...they tend to be painted as clear-cut bad guys, and every time we almost
have a legit debate in the novels--it gets shoved aside by our "heroes".
As for episodes...well, they help out Archer and Co. in "Demons/Terra Prime". Other than that...well, I could defend other actions of theirs, but...little or nothing clear-cut "moral".
