Let's disregard the propaganda elements of this novel, and talk about the elephant in the room: character design.
The protagonist is a robot. He has no feelings, emotions, or beliefs of his own. Events happen, and the MC reacts to them. People approach the MC, he replies back. The protagonist doesn't even move of his own accord! Everything he does is a mission, the only difference is who the mission is being issued by. Sometimes it's from the government, other times it's from the system. A shounen protagonist is more three-dimensional than this idiot.
