Having googled it, it was Moloch, thanks

One of the demons, i believe Belial, actually advocated continuing war during the council of pandaemonium, on the logic that they are suffering so much in this place that only continuing war could offer any hope of total annihilation as an escape from existence and suffering. I always felt that perspective was the most poignant of the whole work.

Edit: it was Moloch: "If there be in Hell fear to be worse destroyed, what can be worse than to dwell here."

Having just finished reading 'Where The Crawdads Sing' and seeing how most people found the ending twist to be improbable and come out of nowhere, I've convinced that most people don't know how to read symbolism. It was the fireflies all along.
