Jory drew his blade, and tried backing out of something after having been told that there is no going back. Duncan was well justified in his actions, reprehensible as they may seem.
Incidentally, nobody survives becoming a Grey Warden. Some just take longer for the taint to kill. Like, say, 30 years.
Keeping the secret is the only way to fight the Blight. Why? Because no Grey Wardens means no way to end a Blight. If the people thought the Wardens were tainted and turned on them, then the Wardens would not be there to defeat the Archdemons, and the world would end. Period.
Dumat's blight lasted 90 years without the wardens, 2 years after the Wardens were formed.
Zazikel's blight lasted 90 years with the wardens.
Toth's blight lasted only 15 years.
Andoral's blight lasts 8 years with the wardens. [I kept missing Andoral's blight oh well

]
310 years later, Urthemial's Blight is resolved within this game, and quite possibly subsequent games, since I doubt any blight would last so short.

During those 310 years though, we have the Wardens manipulating local politics, continuing to exist, drinking the blood of an archdemon and the darkspawn to continue to exist as an organization. And we see members of the organization [Avernus specifically] who don't appear to have any problem exploiting their political standing for their own projects.
Keeping the secret only assures that all other nations depend on the Wardens, and further not seek another solution, if the Wardens are even truly a solution.
