When we do evil things, our thoughts will come back to haunt us in our quiet moments, and condemn us. Trying to live with a guilty conscience is like trying to live with oneself condemning oneself. When the voice of conscience becomes louder, we live in fear of being found out and of the consequences that will catch up with us for the evil we have done. This is true for a murderer, a molester, an adulterer or a criminal. We are haunted all the time, so much so sleep evades us. When we live a life of sin, our conscience will haunt us in our dreams, when we are quiet, or when we are at prayer.
