I disagree. I never liked Cassius, he was arrogant, selfish, and he had many chances to change and didn't take them. For the same reason I didn't like Roque. Roque was supposed to be the more progressive reformer that wanted a good world, and his reaction to Darrow being a red doesn't show that. However, the power of the series comes from the pure awesomeness of the conquering institute, reaping scythe, and pretty much whatever Darrow does. I was impressed with the feelings and thoughts that reading those scenes provoked.
