I think sisko did the right thing.
He realised it was a GRAVE situation.
Look at it this way. Say you were Churchill or FDR and you needed the Soviets to enter WWII, because if not Hitler could win. Wouldn't you do some.....underhandedness if it lent to the greater good???
Sisko isn't a monster. He's just more willing to break the rules, provided it gets the job done. Even more "moral" Captains like Picard did, he was even willing to fight the Borg and it took Lily to talk him out of it. Rules are meant to be broken anyhow.
