Dr. Erland counteracts the stereotypes about Lunars here. While he acknowledges that people like Queen Levana and Sybil Mira are willing to perpetuate crimes against their own citizens to maintain their power, not all Lunars would do the same. In this way, the stereotypes that Cinder (and Earthens more generally) harbor about Lunars are misguided. Dr. Erland has sacrificed himself just like Cinder has, putting his own well-being at risk so that he could escape oppression, come to Earth, and help with letumosis research.
