Actually, it is not shown in the Bible that the devil is ruling in Hell and tormenting souls, but that now the devil “as a roaring lion, walketh about, seeking whom he may devour”, (1Pt. 5:8) and that Hell is a place of ongoing torment, (Lk. 16:19-31) which the lost end up in for because of their sins and spurning their day of grace.
But which is a place of basic punishment as souls await their actual sentencing by the Lord Jesus at the Great White Throne Judgment, (Rv. 20:12-15) in which believers will take part, and it includes sentencing fallen angels.(1Cor. 6:3)
