These people running the tests are fucking fools. They repeatedly tell him to treat the people around him with respect and care, yet everything about the tests says they aren't really people at all. They can reset time, so nothing MC does has any lasting consequences for the world or the people. Other candidates have done objectively worse things is certain situations for selfish reasons, yet MC is trash because everything he does is selfish. Even when sometimes it turns out better for the world anyway. When they have already admitted that nothing he does really matters to the world and people, meaning he is the only person that actually matters at all.
They are telling him nothing he does to others matters, yet admonish him for being selfish. When the self is the only thing that matters. Fucking. Fools.
