Amazing story ruined by one single fatal flaw

Perhaps the biggest disappointment I’ve ever had in fiction. The main reason why I stuck with this series for so long is because almost everything about it is executed incredibly well. The story, worldbuilding, and combat system are engaging and exceptional, and the characters feel genuinely multifaceted. From pacing to emotional beats to long-term character development, the series consistently shows a high level of care and competence in what it’s trying to do.

And here lies my biggest problem with the story: the main character.

I’ve always viewed the main character as a mentally stunted individual, someone who never truly had (and actively rejected) the chance to grow as a person. After shutting himself away in his room, his only real connection to the outside world was through the internet, filtered entirely through his own distorted perspective. Rudeus’s actions before his reincarnation are the main reason I ever believed in him. Standing up to someone being bullied, and more importantly dying while trying to save someone from getting hit by a truck, are why I see him as fundamentally a good person at heart, despite how broken and emotionally underdeveloped he was. Those moments made me want to stick with him, to believe that with a second life he could let go of the views formed from years of isolation and actually grow into someone better.

And in a lot of ways, he does. He develops accountability and empathy, self-control and responsibility. He grows emotionally, socially, and functionally, and nearly every flaw he has is examined, challenged, or gradually corrected. The story executes this extremely well, which is part of why the series appealed to me so much and continued to keep me engaged. The problem is that his ethical growth remains static in one specific area. His views on pedophilia are never meaningfully challenged (either by himself or by the narrative) and this is the only place where the story seems unwiling to engage critically. Everything else is handled with care. Because of how well the rest of the story is executed, this lack of attention stands out sharply and creates a major disconnect with the series’ strong focus on growth and redemption.It also feels like it missed a big opportunity. The story could have used this to meaningfully contrast modern moral values with the older morality of the isekai world, given that Rudeus retains memories and perspectives from a modern society (albeit a highly filtered and skewed one from the internet). There was real potential to explore internal conflict, cultural dissonance, or even gradual moral realignment. Instead that contrast wasn't given much attention. And att this point the only explanation that makes sense to me is that the author simply does not view this flaw as something that needs to be addressed. That is the only reason I can see for why it remains untouched when literally everything else receives such deliberate attention. If the story truly treated this as a moral failing, it would have been confronted like the others and the majority of the storyline would likely have changed. The fact that it isn’t is what ultimately makes this so difficult to overlook.
