Previously, it was adequately demonstrated that Rev 20:10 had to be symbolic. For the sake of emphasizing this, here it is again: (Rotherham)

Revelation 20:10 and, the Adversary that had been deceiving them, was cast into the lake of fire and brimstone, where were both the wild-beast and the false-prophet; and they shall be tormented, day and night, unto the ages of ages.

The same symbolism is seen in verses 13-15. Here it is obvious that Hades, Death, and Sheol, because Hades = Sheol, can not be tormented. This gives enough cause to consider this torment totally symbolic.

13And the sea gave up the dead that were in it, and, death and hades, gave up the dead that were in them; and they were judged, each one, according to their works. 14And, death and hades, were cast into the lake of fire. This, is, the second death—the lake of fire. 15And, if anyone was not found, in the book of life, written, he was cast into the lake of fire.

Revelation is not God's only inspired work! The OT contains numerous passages that show what shall happen to the wicked. Here are a few:

Psalm 37:38 But, transgressors, are to be destroyed together, the hereafter of lawless men, is to be cut off.

Psalm 92:7 When the lawless do thrive like grass, And all the workers of iniquity have blossomed, It is that they may be destroyed for ever.

Psalm 145:20 Yahweh preserveth all who love him, but, all the lawless, will he destroy.

Proverbs 15:11 Hades and destruction, are before Yahweh, how much more then, the hearts of the sons of men.

Isaiah 26:14 The dead, come not to life again, The shades, do not arise,—Therefore, thou hast visited and destroyed them, And caused to perish every memorial of them.

Isaiah 34:2 That Yahweh hath wrath against all the nations, and indignation against all their host,—He hath devoted them to destruction He hath delivered them to slaughter;

Lamentations 3:66 Thou wilt pursue in anger, and wilt destroy them, from under the heavens of Yahweh.

The language in these inspired words are not symbolic, they are to be taken by their word. Thus a picture emerges.

On page one of this discussion, Jesus referred to Gehenna, a valley of Hinnom where refuse, the dead bodies of criminals, and the carcasses of animals were kept burning perpetually so as to avoid pestilence. The purpose with garbage is to get rid of it, in this case by burning. The burning indicates the complete destruction of this chaff, refuse.

Fire when hot enough destroys all organic material so as to be totally reduced into its basic atomic components. Thus the Second death, Gehenna, and the Lake of Fire is supposed to refer to a total destruction of the individuals that are thrown into these, God's solution to chaff, refuse, and garbage.

When we now meditate upon God's love, etc, as mentioned earlier, this clearly is harmonious with such love and mercy. What loving father would unendingly punish his children for singular acts of evil? Not our loving God.  This also harmonizes with Romans 6:23, "For, and Romans 6:7, "For,the wages of sin, is death" he that hath died, hath become righteously acquitted from his sin."

Where does it say anywhere in the Bible that the wages of sin is everlasting torment? Nowhere!  That's where.  So when Jesus says this:

Matthew 3:12 Whose fan is in his hand, and he will clear out his threshing-floor,—and will gather his wheat into the granary, but, the chaff, will he burn up with fire unquenchable.
