That is not what Revelation says.
But if you want to speculate we do know, having been told, that Christ came to destroy the works of the Devil and sin Itself is basically the sum total of his work. Keeping that in mind I’ve looked at the fires and the worm as mentioned by Christ as possibly representing an internal torment (the worm) and an externally applied wrath (the fire). The worm might be the frustration, like a raging itch that cannot be reached to scratch, of the sin nature of the lost — since they can never be permitted to ever again commit any form of sin or else some work of the devil might be said to remain. That would make the fire, wrath, the force that prevents the lost from ever sinning again.
This actually opens up the way for the LoF to be a response to what the damned unchangeably are rather than what they did (no one is condemned because of what was found in the books but because their names were not found in the Lamb’s Book of Life) and possibly therefore individually exacting ... to one with a raging sin nature proportionally more wrath and to one with a weak sin nature proportionally less ... though still wrath of course.
Such a state, again this is speculation based on what we’ve been told, would also explain why the LoF could never get better or — since there would be no opportunity for the damned to indulge sin — worse. To be a completely static condition, unchanging.
As for the saints, the Lord is described as a consuming fire (and the place of the damned outer darkness). Heaven in His presence is therefore possibly much hotter than the LoF BUT the saints will have a nature in accordance to the Holy Spirit ... we will be not just able to take it but able to enjoy it and thrive in His presence.
