No, Jesus/gospel writers clearly believed in the demonology of the times and it included a devil and a hell.
Early church fathers even used Satan as an excuse for many centuries regarding why older religions also had characters similar to Jesus. They claimed Satan meddled with history to fool Christians.
Matthew 25:41 ESV /
“Then he will say to those on his left, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels.
Revelation 20:14 ESV /
Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire.
Mark 9:43 ESV /
And if your hand causes you to sin, cut it off. It is better for you to enter life crippled than with two hands to go to hell, to the unquenchable fire.
I understand most modern ideas about hell come from other sources like Dante. Neither here nor there. All stories and myths.
I don't know about hell being a literal fire, but I believe that it is eternal separation from God.
Even without the Bible, people know that the devil and demons exist.
Satan copies God. Satan, the Antichrist, and False Prophet is the Unholy Trinity. Satan tempted Jesus to worship him. God has angels. Satan took one third of the angels with him when he rebelled.
Truth and lies are mixed. Just because Dante made up mythology about hell, doesn't mean that there isn't a very real hell.
