Vonn. It depends on the secret. Usually I would say a life is much more valuable. But there are some cases where it is not. For example in WWII, We broke the Enigma code, and Churchill intercepted the German orders to bomb Coventry. He could have tipped off the town so they could evacuate, but to do this would risk the Germans finding out we knew the enigma. Instead he had to let the Germans massacre Coventry, killing thousands of lives. In that case a secret was worth more then thousands of lives....
