Dissonance has a hollow ring to it.
Empty examples have a hollow ring unlike any. Show us the dissonance you see?
Here's an example: A karateka steps in a beating in a train to end the felony battery in progress: Perhaps wasn't dramatic as saving a life, but "combat" has occurred and has positively stopped the suffering although the perp got away, which is OK since the civilian has no power of cohersive arrest.
