text: We do know the devil and his angels are in Hell since Scripture plainly tells us this. (Of course, laughably if it weren't so sad, we have Jesuits who think the devil is just a symbol.)
  
  I take the position a number of Scripture verses strongly imply Judas is in Hell, and the Church prays in the Extraordinary Form on Holy Thursday:
  
  "O God, from whom Judas received the punishment of his guilt, and the thief the reward of his confession: grant unto us the full fruit of Thy clemency; that even as in His Passion, our Lord Jesus Christ gave to each a retribution according to his merits, so having taken away our old sins, He may bestow upon us the grace of His Resurrection. Who with Thee liveth and reigneth in the unity of the Holy Ghost, God, world without end."
  
  Other than that, who is in Hell is not known until the final judgement.
