@Isilel I agree it is probably the average
T ‘s plan for a while in OB but I still think that it is in reaction to whether T can replace dalinar or not as the leader. But even if you are right, then still his grand plan is mah... Did he really think that was going to work?! He was the ruler of all Kharbranth and Jah keved and still odium will not save jah keved. So his idea :
Is a very poor and stupid plan and already has failed! So he has caused so much death and destruction in Jah keved, weakened a really strong nation, for a mere whim that was then proven to be false hope at the end of OB.
Well that goal is achieved already, as long as even a handful of men and women are alive, technically humanity will have been saved. So by saving Kharbranth, he saved humanity!
I mistrust average T and his interpretations of the genius T’s diagram and find it both frustrating and hilarious at the same time, that average T is so wrong but still he has so much confidence on himself that he is actively sabotaging dalinar and actually hurting humans in their battle against odium and it is supposed to be ok because “he has good intentions though!!”
