This proverb focuses on the kind of person who violates the accepted patterns of lawful behavior and is therefore rejected by law-abiding people. The violent or unjust man (אִישׁ חָמָס) has a powerful need to be accepted and therefore he entices (יְפַתֶּה) any likely individual to join his way of life. Mishlei is cautioning such an individual to resist the enticements because although they may seem attractive, they are clearly not good (לֹא טוֹב) and will cause him great harm.
