Honestly, I laughed pretty hard at that one too. Moash has been thinking recently about his Bridge Four days (it's one of the reasons he intervened to help the parshmen), and how he didn't DESERVE the things that Kaladin did for him to get him out of there (including his Shardplate/Blade), and then they finally get to the city's destination and he discovers it's a lumberyard, and THEN it turns out that he and his fellows are going to be running at the tip of the assault, with ladders...
Well, I thought it was pretty funny too, in a grim way. If that makes him crazy and Odium-touched then I guess I am too.
