Proverbs Chapter 1:

24 “Because I called and you refused, I extended my hand and no one took notice;

25 Because you disdained all my counsel, and my reproof you ignored–

26 I, in my turn, will laugh at your doom; I will mock when terror overtakes you;

27 When terror comes upon you like a storm, and your doom approaches like a whirlwind; when distress and anguish befall you.

28 “Then they call me, but I answer not; they seek me, but find me not;

29 Because they hated knowledge, and chose not the fear of the LORD;

The “perfect” man takes pleasure in others' suffering. At least, when it's caused by their own ignorance.
