Does Hell Exist
I'm paraphrasing each verse listed.  Go read if for yourself. 

Deuteronomy 29:19-20 Those who persist in going their own way, will never be forgiven. They are cursed.
Psalms 1:-1-6 God laughs at those who conspire against God and his anointed. They get discipline and God's wrath. He gives the nations as an inheritance to his Son.
Psalms 34:16 God is against the evil, and their names will be blotted out.
Psalm 37:1-2 Don't worry about the evil, soon they will die.
Psalm 37:20 Evil will be consumed in fire.
Psalm 69:28 The evil will be erased from the book of life.
Proverbs 10:25 The evil will pass away like a whirlwind.
Proverbs 24:20 Evil will be snuffed out.
Daniel 12:2 Multitudes are asleep, will rise to life or contempt.
Obadiah 1:15-16 The nations will reap what they sow, and they will disappear.
Matthew 5:22 Even if you call someone a fool, you're in danger of the fire of hell (The orginal word here is Gehenna, which refers to a valley outside Jerusalem, historically associated with idol worship and later used as a garbage dump where fires burned continuously to consume garbage.)
Matt 13:41-42
Everything that causes sin, and everyone that does evil will be weeded out. Thrown into a blazing furnace.
Matt 18:8-9 Better to cut off a part of you that makes you sin, than to be thrown into hell.
Matt 22:13 If you're not clothed properly for the wedding, you're thrown out.
Matt 25:39-41 The cursed, along with the devil and his angels will be thrown into the fire.
Mark 9:43-48 Serve each other. Jesus was servant to the all, including crippled, poor, and destitute.
Luke 16:22-24 Torment in the fire of Hades.
John 5:28-29 Those who do evil will be condemned.
Romans 6:21-23 Sin has no lasting benefit and leads to death. The gift of God is eternal life through Jesus.
1 Corinthians 3:17 We are the temple fo God, anyone who destroys it will be destroyed.
1 Corinthians 15:22 Adam brought death.  Christ brought life. Christ, the firstfruits, then the rest at his return.
2 Corinthians 2:15 We are the smell of death to some, and life to others.
2 Thes 1:8-9 Those who do not know God will be punished with everlasting destruction.
1 Timothy 4:10 God is the savior of all men, especially those who believe. (This is interesting.  Savior of ALL men, especially those who believe. Clearly not all men will be saved.  This makes a strong case for saying that even some who do not believe, will be saved. Goes back to what Jesus said on the cross. Forgive them.. The them was not qualified except by "they know not what they do". We can trust he will judge fairly. Good to be sure though!)
Galatians 6:8 Please the body, reap destruction. Please the spirit, reap eternal life.
Philippians 3:18-19 Enemies of the cross will be destroyed.
Hebrews 10:27 ...but ony a fearful expectation of judgement and raging fire that will consume the enemies of God.
James 1:15 Lust leads to sin, sin to death.
James 4:12 God judges and destroys. Don't slander your brother/neighbour.
James 5:20 Save your brothers from wandering from the faith.
1 John 2:2 Jesus died for the sins of the entire world.
Jude 8:7  ...serve as examples of those who suffer the punishment of eternal fire
Jude 8:13 ...for whom blackest darkness has been reserved forever
Rev 14:10-11 Torment with burning sulphur.
Rev 20:10 Devil, beast, false prophet tormented day and night for ever and ever.
Rev 20:14-15 Death and Hades thrown into the lake of fire to be destroyed, along with those who's names are not written in the book of life.
Rev 21:8 ...the fiery lake of burning sulpher. This is the second death.

And the answer is Yes, there is a hell.  And it appears for some it will be eternal torture, for some destruction. But it does look like Hades and the "lake of fire" are two different things.  Hades is either a place of torment or where all the dead go, but the lake is destruction. So, even death and torment will be destroyed in the end when God's plan is complete.
