Lol, okay this is a problem and it explains your opinions over the past few days/months/years regarding Demandred. You still consider him to be Barid Bel Medar, his old self, which is totally untrue.

Is Semirhage still the greatest Restorer of the 2nd Age? Is Graendal still considered to be revered for her simple lifestyle? Of course not! They've all gone down an irreversible spiral of evil. I can't believe you don't think this would have affected Demandred.

Demandred is nearly as strong and skilled as Lews Therin in the Power, but as a man, he's not even a fraction, and character makes all the difference. Flaws are the reasons for the Forsaken's fall from grace. Even the Dark One says it for crying out loud. Rahvin... dead in his pride. Sammael who advertised that he was in Ilian. Lanfear who thought that no one could touch her while she was torturing Rand. Semirhage who thought she could leash the Dragon Reborn and five of his allies unaided.

There is an essential theme around the Forsaken i.e. their great natural skill but their waste and perversion of it. Therefore, I think I'm the one who's read Demandred properly. You still think of him as one of Lews Therin's gifted generals. In power he's lost little, but in character he's lost everything. It's thus completely accurate to say that he could be taken down by a thorn in his foot. Perhaps Barid Bel Medar would have died in a blaze of glory, but Demandred will get nothing - just like every other Forsaken. Unless, of course, you think death by mashadar is what a man of Sammael's stature was worth?
