Whether we want to admit it, revenge is a bona fide motivator. But is it healthy?

Well … yes and no.

“In novels and movies, revenge turns out to be this great cleansing moment that permits someone who’s been abused to triumph,” said Peg Streep, a science writer and author of “Mean Mothers: Overcoming the Legacy of Hurt.”

“Revenge works well in plot lines because there’s something very satisfying about a tit-for-tat payback, especially in a world that isn’t always fair,” she said.
