2 Sam 12: 5 Then David's anger was greatly kindled against the man, and he said to Nathan, “As the Lord lives, the man who has done this deserves to die, 6 and he shall restore the lamb fourfold, because he did this thing, and because he had no pity.”

Here is an example where David was quick to recognize the sins of others, but slow to see it in himself.

Luke 6:42 How can you say to your brother, ‘Brother, let me take out the speck that is in your eye,’ when you yourself do not see the log that is in your own eye? You hypocrite, first take the log out of your own eye, and then you will see clearly to take out the speck that is in your brother's eye.
