I can scarcely believe that Aminar was the first, and only, to mention Szeth the sociopath as their least favorite.
He runs about committing regicide for the first two books hiding behind the convenient lie that "I have no choice but to plunge the world into chaos" which would better read as "Since I'm such a useless bloke, I'm going to kill everyone that is a better man than I am. Oh, and I'm going to use a magical weapon to do so, because I have no power of my own."
I realize that some people see the "honor" in his choice of being an assassin, one that doesn't even get paid, much more like a chained hound, but I just see him as a weak willed child with no true character.
Oh, and swearing an ideal and following Dalinar all of a sudden does not forgive you your crimes, it's another copout. It'd be like that vegetarian painter, name of Adolf Hitler, giving some pretty pictures to the Jews and saying "Oh, my bad guys."
