While double killing is the only way to find someones identity it does rob us of an opportunity to rid ourselves of a malevolent crewmember. Short of a protector save the agressors are going to kill each night. They are not going to kill one of their own surely and are unlikely to doublekill - and if they did it might be as a bluff rather than a certain indication that a ghost were being too perceptive. There are times for damage limitation but we can't afford to routinely doublekill people. I am inclined to take Greenie's word for now myself.
