That does not mean that he cannot just wipe us all out. Him being as empty as the Void is just kinda how we looks he probably can wipe off all of earth clean.

And he may not actually care for the Brotherhood as suggested above.

By the way, why kill them? I did all their quests, got Shadowmere, the summon spell, their uniform, the 20K from killing the Emperor, then ran away.
