"Those who have become fully established in this soul-and-body-destroying vice can seldom rest until their burden of secret evil is imparted to those with whom they associate. Curiosity is at once aroused, and the knowledge of vice is passed from youth to youth, from child to child, until there is scarcely one to be found ignorant of the practice of this degrading sin. 2T 392.1"
"For they sleep not, except they have done mischief; and their sleep is taken away, unless they cause some to fall."
Both passages describe the restless nature of those who engage in evil, specifically their compulsion to involve others in their wrongdoing. Proverbs 4:16 speaks of a general desire to cause others to fall, while the EGW passage focuses on the spread of knowledge about 'secret vice.'
