Claude deserves a little moral ambiguity. As a treat.
I wasn't expecting much from this game's story, but it's incredible seeing stories tailored for each of the lords. I like seeing how each of them reacts to an accelerated timeline and lack of Byleth's guidance, and how Claude (who arguably had it best post-timeskip) suffers for it.
Having lost his chance to find someone to trust in, confronted with the divided Leicester Alliance, and adding blood to his hands is fantastic to see Claude crack a little.
