Yeeaaahhh He's terrible and no one likes him, but I still feel like he just needs a spren buddy. Like, Dalinar murdered thousands and burned an entire city to ashes with the specific intent to make sure no one would ever dare live there for generations. He took like a long time to realize that maybe mass murder and genocide weren't very cool. Moash has been at this whole revenge thing for like a few years at most? He only started taking Odium's Antidepressant (Never Fails!*) recently. Dalinar's been chugging the Thrill for years.
Ok, just to be clear, I do agree Moash is a...How shall I put this...rather unsavory individual, but he still has some depth (like a kiddie pool depth, but still depth?), and enough that I wouldn't be upset if he got a redemption arc that also involves being thrown off Urithiru without an Honorblade. Ok enough rambling from me.
