John Chrysostom — as excerpted in the Catena Aurea on Mark 5:1-20

“(Vict. Ant. e Cat. in Marc. et v. Chrys. Hom. in Matt. 28) Then praying to Him, he subjoins, I adjure thee by God, that thou torment me not. For he considered being cast out to be a torment, or else he was also invisibly tortured. For however bad the devils are, they know that there awaits them at last a punishment for their sins; but that the time of their last punishment was not yet come, they full well knew, especially as they were permitted to mix among men. But because Christ had come upon them as they were doing such dreadful deeds, they thought that, such was the heinousness of their crimes, He would not wait for the last times, to punish them; for this reason they beg that they may not be tormented.”
