> Technically it wasn’t the disease which defeated the Founders, though I supposed one can argue it debilitated them enough.

It put a countdown clock on their remaining lifespan. Infecting all the Founders simultaneously with a lethal disease made the entire war (that they were very much winning) moot. For the Founders, the entire reason behind the conflict was to ensure their own safety from hypothetical future threats (they were a paranoid bunch); that obviously is not achieved when all Founders are dead, so the entire calculus changes.

That's what I mean by saying that the virus short-circuited the war. It may have been the compassionate and extremely risky act of Odo that, in true Star Trek fashion, changed hearts and minds and got everyone back to the negotiating table, but even without it, the virus would've ended the war within a week or such - leaving alpha and beta quadrants in a bad state (fighting against now feral but still superior Dominion invasion force), but still much better and more survivable than the war itself was.

> Even so, despite the results I didn’t feel like the show was necessarily approving of Section 31 (the main characters actively tried to defeat them).

The show was very much not approving of Section 31; that one was communicated quite clearly. What I'm saying is that, if you ignore what you're being told and look at what you're being shown - the events that happened, not the main characters' opinions on them - it's becomes much harder to paint Section 31 as villains of the story.

I believe this outcome was not intended by the writers; it's just what the whole storyline ended up adding up to.
