 That's what a bitter person does, from one person to another, running their mouth, running people down, slandering people, the ones they hate, trying to get you to hate them also. Paul even states this in Ephesians 4.31, this type of self-induced fault leads to slander, and it's repeating a public lie, so that if you tell it often enough, and if you tell it long enough, it's going to be believed eventually.
