Jesus said to the disciples:
“The Kingdom of heaven is like a net thrown into the sea,
which collects fish of every kind.
When it is full they haul it ashore
and sit down to put what is good into buckets.
What is bad they throw away.
Thus it will be at the end of the age.
The angels will go out and separate the wicked from the righteous
and throw them into the fiery furnace,
where there will be wailing and grinding of teeth.”
“Do you understand all these things?”
They answered, “Yes.”
And he replied,
“Then every scribe who has been instructed in the Kingdom of heaven
is like the head of a household who brings from his storeroom
both the new and the old.”
When Jesus finished these parables, he went away from there.
The separation of people to good or bad. The obvious question here is what is it really meant to be good? Do we need to quote verses from the bible to know what is good to do? Do we still need to know how to be good from preachers?
The Lord made us to be His reflections hear on earth. It is in our nature that to do good is the first thing you will hear on our conscience. There was never really something that 'you feel good when doing bad things'
That would be insanity or the person may be being dishonest with himself. Setting aside the image of God within him.
The question if hell is really real is not the point here. We do not need to prove that hell is real for people to be afraid and be conscious of what we are doing. Be yourself, and the good in you shall prevail.
