Judas Iscariot was one of the twelve disciples of Jesus Christ, who was known for his betrayal to Christ. He told the Sanhedrin chief priests and scribes, who wanted Jesus put to death, that he would hand him over for thirty pieces of silver.
After Jesus was arrested and sentenced to death, Judas, realizing the atrocity of his betrayal, tried to return the pieces of silver to the chief priests. After they refused, Judas flung the coins into a temple, and killed himself by hanging. There are two different versions of Judas Iscariot's death in the Bible.
The version more widely known is where Judas hangs himself. The other claims that Judas fell, split his stomach, and his entrails fell out.
His betrayal has become infamous enough for the name Judas to be used as a common term for a traitor of any kind, especially one that betrays a close ally.
Judas was sentenced to the ninth circle of Hell, the circle of Treachery. Due to his actions, he has been labeled among the greatest traitors in history, along with Brutus and Cassius, the murderers of Caesar. All three have been sentenced to the ninth and final circle of Hell. Unlike the other traitors, who are frozen in ice, Judas, Brutus, and Cassius are eterally punished by being gnawed upon by the three heads of Satan. Judas, headfirst in Satan's middle head with his back raked by Satan's claws, suffers the worst punishment of the three.
