[OB] What could the Fourth Windrunner Ideal be?

[Ripheus23]

I feel like Kaladin could be self-deceived about the plausibility of his efforts succeeding. He might think that he actually can save everyone he helps, and he might think that if he didn't believe his efforts could be successful, he would give up on them. Now as for the 3rd Ideal, both examples of it that we've seen involve a reference to hate, and hate is the emotion of Odium himself, so I think there's a reason for it to be referred to, here.
