One of the things that delights me most about the Forsaken is that most of them so badly want to be more then human, and what drives that desire, that need to transcend mere mortality varies from Forskaken to Forsaken, from sheer pride (Lanfear), to fear of death (Asmodean), to a need to escape mortal weakness and pain (Graendal), to simple desire to be seen and to matter (Moghiden) but no matter how hard they run, no matter how much power they gather, what armies they command, what rules of reality they defy, they are still painfully inescapably human. Even cheating death dosen't change that.
They are still petty and caring and cruel by turns, Lanfear still loves Lews Therin in a way she can never deny, Moghiden still can't conquer the fear that controls her, Graendal can not bury her heartache deep enough, Asmodean can not undo the past, Demandred can never convince himself he is good enough, Semirhage can not satisfy her thirst for control, Messana can never convince herself she is brilliant enough to feel truly validated.
The Forsaken are caged by the humanity they want to reject. They imagine themselves as god kings in waiting, who will remake the world in their own image when the Dark One wins, but they are no more boiled down to the bones of who they are, then those they want to subjugate, just flawed, just as painfully, overwhelmingly human as the heroes, and the failure to realize that is what is their undoing.
