“Eternal Torture”, as a concept, was invented by Catholics in the dark ages.

The lake of fire and brimstone is eternal torture. If you are not satan, its the lake of fire what is meant. It is eternal separation from God. The God that made you and Creation. To be separated from Him is to live life without living, eternally without any life. Eternal darkness. To say, without all the good the universe has to offer. You’re left with nothing but the worst humanity, the spiritual world and the universe has to offer. And it is called the second death, its eternal and not long sleepy rest death like when your earthly body ceases.
