This is an excerpt about finding out too late about evil:
"When evil weasels its way into power, those who once doubted the existence of evil might change their minds when they see how wicked men behave when they are in power. Those who are crushed by tyrannical evil powers might quickly cast aside their doubts about the existence of evil--but then it may be too late. It is too late for a lamb to flee the wolf when it is in the wolf's mouth. Free men can fight evil, but those in dungeons cannot--unless they are spiritual heroes like the Apostle Paul in a Roman jail, or moral heroes like Solzhenitsyn in a Soviet gulag."
