Well, in my depiction of hell, hell is somewhat of a imaginary prison, all sinners, demons and the seven six think lucifer (or satan in the case) is preparing some big revolution against heaven.
He isn’t.
He hates all of hell, he hates the people following him, he thinks as the biggest prisoner of hell.
Even when Lilith tries to cheer him up he answers “Hope in reality it is the worse of all evils.”
I think of him like: a nihilist that is a nihilist because god is real, and there is no chance against winning.
And this is just a funny sitcom in hell I have in mind
