One of them may redeem us. One of them will destroy us.

In the back of WOK, this is present which is supposedly from the sleepless -

'I long for the days before the Last Desolation. Before the Heralds abandoned us and the Knights Radiant turned against us. When there was still magic in the world and honor in the hearts of men. In the end, not war but victory proved the greater test. Did our foes see that the harder they fought, the fiercer our resistance? Fire and hammer forge a sword; time and neglect rust it away. So we won the world, yet lost it. Now there are four whom we watch: the Surgeon, forced to forsake healing and fight in the most brutal war of our time; the Assassin, who weeps as he kills; the Liar, who wears her scholar's mantle over a thief's heart; and the Prince, whose eyes open to the ancient past as his thirst for battle wanes. One of them may redeem us. One of them will destroy us'

Assuming the above is related to what happens after book 5 and before book 6, I assume the one who destroys is Dalinar (as far as everyone is concerned, Dalinar lost the contest and gave up Honor to Taravangian) and the one who may redeem us is Kaladin (as he takes away Odium's darkness from the heralds and reinstates the Oathpact)?

Curious as to what everyone else thinks on this...
