Whether there is sorrow in the demons?

Objections

Objection 1 : It would seem that there is no sorrow in the demons. For since sorrow and joy are opposites, they cannot be together in the same subject. But there is joy in the demons: for Augustine writing against the Maniches (De Gen. Contra Manich. ii, 17) says: "The devil has power over them who despise God's commandments, and he rejoices over this sinister power." Therefore there is no sorrow in the demons.
Objection 2 : Further, sorrow is the cause of fear, for those things cause fear while they are future, which cause sorrow when they are present. But there is no fear in the demons, according to Job 41:24, "Who was made to fear no one." Therefore there is no grief in the demons.
Objection 3 : Further, it is a good thing to be sorry for evil. But the demons can do no good action. Therefore they cannot be sorry, at least for the evil of sin; which applies to the worm of conscience.
