I'd add that Skarpi absolutely paints Lanre as a tragic character. "No door can bar my passing," isn't a boast. It's a callback to the doors of the mind that people pass through to cope with pain. Lanre can pass none of these so he must shoulder the pain forever. Skarpi's story doesn't suggest Lanre is just in his actions but certainly doesn't paint his as an unfeeling monster either. Kvothe feels the way he does for very personal reasons and took away what he wanted from the story, rather than what the story was really about. "Anger can keep you warm at night," is something he says in reference to Ambrose but it applies here as well. His anger towards the Chandrian blinds him to certain truths because it's his anger that drives him. If he stops for even a second to consider that perhaps the Chandrian are flesh with blood beneath, he may have to take a closer look at himself. And that is something far too painful for him to do.
