They only did that to Stormcloaks. The Battle-Born family tipped the Thalmor in that Thorald  was a Stormcloak spy/soldier/ally even though he wasn't until after the quest Missing in Action. Other than that, he's the only specifically mentioned person they tortured. And either way, that's besides the point. People will still worship Talos so long as they're still living (unless they believe in another religion entirely which is also besides the point).
