BIBLICAL REASONS THAT A GOD WOULD NOT LET PEOPLE SUFFER AFTER DEATH
What does the Bible say are the best ideas in the Bible ?
1 Cor 13v1 & 13 The greatest of these is love
 Matt 7v12: Golden Rule:  Do to others what you would have them do to you, for this sums up the Law
Matt 22v39 The second greatest commandment is love your neighbour as yourself. All the law hangs on this
John 13v34 A new commandment I give you, you must love one another
Romans 13v10 Love does no harm to its neighbour. Therefore love is the fulfilment of the law
1 John 4v8 God is love : therefore does no harm to his neighbour
Luke 6v37, Do not judge that you be not judged. Do not condemn that you be not condemned, forgive that you be forgiven,
After teaching the disciples the above verses  Matt 16v19Jesus delegates authority to keys of kingdom of heaven to Simon Peter, so surely you would expect Peter to judge according to above principles
Think of the Magna Carta which is the principle that the King should have to abide by the law of the land.
Now use the above principles to ask how you would expect Jesus / God to act if he was to act in accordance with those principles.
Matt 7v12 Jesus should ask himself if he would like to spent eternity in a hell ? Obviously no, and as Ephesians 5v29 says: After all no sensible person ever hated his own body but he feeds and cares for it.  Genesis 1v29 God is in mans image so should empathize
So since Jesus would not like to go to a hell he should not let others- especially not most of humanity go to a hell.
James 4v17 Anyone ( including God ) who does not do the good he should sins
Jesus would condemn himself if he condemned most of humanity
Surely a God would act in accordance with Geneva Convention Part 1 article 3a which bans torture
Jesus would not be able to forgive himself unless he forgave everybody
Matt 18v22 Jesus answered forgive seventy times seven
John 14v14 You may ask me for anything in my name and I will do it .
 Matt 19v26  For God all things are possible
Maybe some of  the ideas in the Bible do not conform to the image of Christ as above ? Romans 12v2
So Jesus or the disciples should have asked that humanity either go to heaven or extinction, not a hell
Luke 23v34 Jesus should have said, " Forgive all humanity and take them to heaven for they know not what they do " and he would have received that prayer request, according to John 14v14
John 3v16 should read: " For God so loved the world that he could not bear the thought of condemning anyone and it would blight his conscience and so he saved everyone through Jesus. "
HAPPY EVER AFTER, AMEN
