Meaning

Do wrong; wrong or injure someone.

Grammatical category: verb.

Use in the book

The verb explains why one wicked person becomes more hostile to another through closer association: he does wrong. Active and passive participles then distinguish wrongdoers from those wronged.

The claim that such parties cannot be friends is used to challenge the unrestricted friendship of like with like. The verb is relational here, specifying action against another person; it should not be collapsed into merely possessing the adjective “bad.”
