I hate Riku so much. I can understand his point of view and there isn't a lack of logic, The fact this episode is spotlighting his self-righteousness is honestly absurd and I want to toss him off a cliff. The resolve to be right doesn't make it right. This is an episode that celebrate hubris, it's honestly infuriating. At the very least, I can appreciate the fact the episode is acknowledging the risk and deaths caused by his way of teaching.
