Something that distinguishes the character is the perfect notion that the devil is always walking, always at the side, lurking in wait for the slightest falter. Lose fear of him for an instant and the fall is almost certain. Only fools do not realize it. And those who are not foolish, sometimes well aware that there is nothing to joke about, experience the indescribable distress and terror that comes from realizing how weak the flesh is and how low, for how little, it can descend. To have character is, to a large extent, to become accustomed to incessant vigilance.
