To retaliate (against a person, group, organization, etc.) for a wrong done to oneself; to seek or exact revenge (against someone or something). Tiffany is always gossiping about me, so I got revenge by starting a nasty rumor about her. Getting revenge will never give you a sense of peace or closure—you'll remain just as angry as before, and it will bring suffering to someone else along with you.
