Judas Iscariot died by suicide, after having betrayed Jesus and having seen that he was condemned to death. He repented of having betrayed Jesus when he saw the outcome of his sentence, but nonetheless, could not bear his guilt. Pope Benedict XVI said, “[Judas] repented, but his repentance degenerated into desperation and thus became self-destructive.” The account of his death can be found in Matthew 27:3-5. “Throwing down the pieces of silver in the temple, he departed; and he went and hanged himself” (Matthew 27:5).
