Then Judas, which had betrayed Him, when he saw that He was condemned, repented himself, and brought again the thirty pieces of silver to the chief priests and elders, saying, I have sinned in that I have betrayed the innocent blood. -Matthew 27:3-4

Yes, Judas the traitor, who had betrayed his Master, when be saw that his Master was condemned, “repented, and brought again the thirty pieces of silver to the chief priests and elders, saying, I have sinned, in that I have betrayed innocent blood, and cast down the pieces in the temple, and went” and what?- “and hanged himself.” Here is the worst kind of repentance of all; in fact, I know not that I am justified in calling it repentance; it must be called remorse of conscience. But Judas did confess his sin, and then went and hanged himself. Oh! that dreadful, that terrible, that hideous confession of despair! Have you never seen it? If you never have, then bless God that you never were called to see such a sight. I have seen it once in my life, I pray God I may never see it again -the repentance of the man who sees death staring him in the face, and who says, “I have sinned.” You tell him that Christ has died for sinners; and he answers, “There is no hope for me; I have cursed God to His face; I have defied Him; my day of grace I know is past; my conscience is seared with a hot iron; I am dying, and I know I shall be lost!”

Ah! There may be a man (reading) here who may have such a death as that; let me warn him, ere he come to it; and may God the Holy Spirit grant that that man may be turned unto God, and made a true penitent, and then he need not have any more fear; for he who has had his sins washed away in the Saviour’s blood, need not have any remorse for his sins, for they are pardoned through the Redeemer. ~ C.H. Spurgeon
