Moash is a villain and I accept him as such. Lirin tries to 'help' Kaladin but is OK with giving up his son to the enemy because he is 'dead to him'. He is just not a good father.
I do appreciate waves and their link to Cosmere. My favorite character right now is Shallan, though it's a function of my mood and if you ask me this question later, I might have a different answer.
I am currently a Physics student at UofA. I am on a mission to complete reading the entire Cosmere. I have finished everything except for Sixth and White Sand. I hope I'll be able to have interesting discussions.
