" To do something, to do what you feel sure is right and in the aid of justice, you sometimes have to do things that, when recalled on lonely nights, make you wonder if in fact you are the good man that you like to believe you are. Such doubts are high cards in the devil’s hand, and he knows how to play them well, in hope of bringing you to despair and ennui, if not to self-destruction. "

― Dean Koontz , Odd Hours (Odd Thomas, #4)
