25. The Lord is called the Son of man when the subject is judgment. This is clear from the following:

When the Son of man comes in His glory..., then He will sit on the throne of His glory. And He will set the sheep on His right, and the goats on the left. (Matthew 25:31, 33)

...when the Son of man sits on the throne of His glory..., He will judge the twelve tribes of Israel. (Matthew 19:28)

...the Son of man will come in the glory of His Father..., and then He will repay each person in accordance with his works. (Matthew 16:27)

Watch...always, that you may be held worthy...to stand before the Son of man. (Luke 21:36)

...the Son of man is coming at an hour you do not expect. (Matthew 24:44, Luke 12:40)

...the Father judges no one, but has committed all judgment to the Son..., because He is the Son of man. (John 5:22, 27)

The Lord calls Himself the Son of man when the subject is judgment because all judgment is made in accordance with the Divine truth that is in the Word. That this is what judges everyone is something the Lord teaches in John:

If anyone hears My words and yet does not believe, I do not judge him; for I did not come to judge the world.... ...the Word that I have spoken, it will judge him in the last day. (John 12:47-48)

And elsewhere:

(The Son of man did not come) to judge the world, but that the world through Him might be saved. He who believes in Him is not judged; but he who does not believe is judged already, because he has not believed in the name of the only begotten Son of God. (John 3:17-18)

That the Lord does not judge anyone to hell or cast anyone into hell, but that it is the evil spirit himself who judges and casts himself, may be seen in the book Heaven and Hell 545-550, 574.

The name of Jehovah, of the Lord, and of the Son of God, means Divine truth, thus also the Word, which originates from Him, is about Him, and so embodies Him.

574. I explained above (548) that evil spirits voluntarily throw themselves into hell, so I need to state briefly why this happens when there is such torment in hell.

From each hell there breathes forth an aura of the cravings that obsess its inhabitants. When this aura is sensed by people who are obsessed with a similar craving, it touches their hearts and fills them with delight because the craving and the delight are inseparable - whatever we crave is delightful to us. This is why spirits turn in that direction and are impelled there by their hearts' delight. They do not yet realize what kind of torment there is in hell, and the ones who do know still feel the craving. In the spiritual world we are all incapable of resisting our impulses because the impulses come from our love and the love comes from our intent and the intent comes from our nature, and we all act from our nature there.

[2] So when spirits voluntarily or freely arrive at their hell and go in, they are accepted cordially at first and think they have arrived among friends. This lasts only a few hours, though. All the while they are being probed to find out how crafty they are, and therefore how powerful. Once this probing is complete the attacks begin in various ways, getting more and more severe and intense. The intensification is effected by their being taken farther and deeper into hell, since the farther and deeper you go there, the more malevolent are the spirits. After these attacks, the malevolent spirits begin to torment the newcomers with punishments until finally they are reduced to slavery.

[3] However, since rebellious movements are always arising (everyone there wants to be greatest and burns with hatred against everyone else, which keeps generating new attacks), the scene is constantly changing. The people who were enslaved are released and offer their support to some new devil for the subjugation of others. Then the ones who do not surrender and yield their obedience are tortured in various ways, and so on and so on.

Torments like this are the torments of hell that are referred to as hellfire.
