The Dominion war story gives a clear message that humans, during crisis, are no different in the 24th century, than they ever were.
When these two topics are discussed, it's usually focused on the morality of Sisko, or Garak, or "Section 31." It appears that Starfleet is quite complicit in both instances.
In In The Pale Moonlight, Sisko explicitly mentions that Starfleet command approves his mission to trick the Romulans. What he sets out to do is such a huge gamble, that we can imagine this approval would come from the highest levels of government. And of course, the Federation is rewarded for their deception.
As for the virus, when Bashir contacts Starfleet Medical to get Odo's medwork, he's denied. They give him subtle accusations of treason for wanting to cure Odo. They want the virus to succeed. If it had, the Federation would have been rewarded. In the end, Odo uses the cure as leverage to get the founder to surrender. So the Federation is still rewarded.
So I agree. This is one of the biggest messages of DS9.
In contrast to much of Treks usual message of 'virtue is it's own reward', the Federation win the Dominion War largely because of two very unpleasant acts in their part - conning the Romulans into joining the war, and infecting the Changelings with a disease. It is unlikely they would have won without these acts, and yet they fly in the face of the Federation's values. I wonder how Sisko, one of the few men aware of both, feels about that.
