What does 2 Samuel 19:6 mean?

'You act like you love those who hate you and hate those who love you. You’ve made it clear today that your commanders and soldiers mean nothing to you. I honestly think you’d be happier if Absalom were alive and all of us were dead.' 2 Samuel 19:6 - Modern Text Bible

(Joab bluntly accuses David of caring more about his rebellious son than about the people who stood by him.)
