Actually, Hades fire was the teaching of the Pharisees, a place where sinners would suffer from blasts of heat and cold, from burning coals in mouths that spoke blasphemy, lisencious men hanging from genitals etc. Jesus used their own ridiculous teachings in satire to counter their justification for not lifting a finger to help the poor.
The Pharisees were not permitted to help the poor in the slightest because such would be countering God’s judgment. Accept God’s redemptive judgment and you will be rewarded in Abraham's Bosom in the afterlife. In Luke 16 Jesus has Abraham turning the tables on the Pharisees in the afterlife as they end up in the very hell they warned the common people to avoid for no reason other than they had good things in life. This is obviously a parody.
