Luke 16:23; "In Hades he lifted up his eyes, being in torment, and *saw Abraham far away and Lazarus in his bosom.
Luke 16:24; "And he cried out and said, 'Father Abraham, have mercy on me, and send Lazarus so that he may dip the tip of his finger in water and cool off my tongue, for I am in agony in this flame.'
Luke 16:25; "But Abraham said, 'Child, remember that during your life you received your good things, and likewise Lazarus bad things; but now he is being comforted here, and you are in agony.
Luke 16:28; for I have five brothers—in order that he may warn them, so that they will not also come to this place of torment.'
As other's have mentioned, hell isn't the worst of it.
Rev 20:13; And the sea gave up the dead which were in it, and death and Hades gave up the dead which were in them; and they were judged, every one of them according to their deeds
Rev 20:14; Then death and Hades were thrown into the lake of fire. This is the second death, the lake of fire.
Hell is a temporary place that eventually will be thrown into the Lake of Fire. Eventually everyone is Hell will be freed long enough to face the judgment.
Rev 20:10; And the devil who deceived them was thrown into the lake of fire and brimstone, where the beast and the false prophet are also; and they will be tormented day and night forever and ever.

Matt 18:9; "If your eye causes you to stumble, pluck it out and throw it from you. It is better for you to enter life with one eye, than to have two eyes and be cast into the fiery hell.

2Pet 2:4; For if God did not spare angels when they sinned, but cast them into hell and committed them to pits of darkness, reserved for judgment;
2Pet 2:9; then the Lord knows how to rescue the godly from temptation, and to keep the unrighteous under punishment for the day of judgment,
2Pet 2:10; and especially those who indulge the flesh in its corrupt desires and despise authority. Daring, self-willed, they do not tremble when they revile angelic majesties,
There are people who believe God won't do any of this, but they are deceived. The Bible clearly says He will.
Rev 20:15; And if anyone's name was not found written in the book of life, he was thrown into the lake of fire.
For those who think hell is simply separation from God...
Rev 14:10' he also will drink of the wine of the wrath of God, which is mixed in full strength in the cup of His anger; and he will be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb.
"in the presence of the Lamb". Jesus will be there watching.
[KJV] Psa 139:8; If I ascend up into heaven, thou art there: if I make my bed in hell, behold, thou art there.
God exists everywhere, even in hell.
