Regret

20 But Abiathar, a son of Ahimelech son of Ahitub, escaped and fled to join David. 21 He told David that Saul had killed the priests of the LORD. 22 Then David said to Abiathar: "That day, when Doeg the Edomite was there, I knew he would be sure to tell Saul. I am responsible for the death of your father's whole family. 23 Stay with me; don't be afraid; the man who is seeking your life is seeking mine also. You will be safe with me." 1 Samuel 22:20-23

Have you ever seen it coming?

David did, and at this point he probably realized he should have taken it more seriously. If David had spoke the truth then maybe Ahimelech could have at least prepared for the trouble, he possibly could have stopped Doeg.

Can you imagine the regret David carried?

Because of his inaction a whole community was destroyed and David probably carried those scars for a long time.

I've made mistakes like that, which has taught me to confront things early. I'm still learning how to do that, but it does come with some cost. Be prepared to be labeled judgmental and prideful; but would you be willing to be called that to save a whole community?

Then, there are those times you were just wrong about your assessment. Those are times to practice humility and understanding, which can lead to better intimacy. It's better to bring those things out than to let them fester and grow inside of you, that whole root of bitterness thing. Bring it out in the open, the light to be seen for what it is.

20 All who do evil hate the light and refuse to go near it for fear their sins will be exposed. 21 But those who do what is right come to the light so others can see that they are doing what God wants."
John 3:20-21

When prompted take action, for if you don't you may have to live with regret.
