Resentment keeps us focused on a perception of unfairness, and justice wants to scream out for equilibrium. The “wronged” person feels that they are not getting the help, appreciation, reward, or affection that they deserve. They feel like the betrayal is too deep, and the other person hasn’t “paid” enough for their dishonorable behavior. Even though there may be substantiating evidence to prove those very points, justifying resentment only strengthens and prolongs it.
