Adults can be evil
Sensei just says Child cannot be evil

2/3rds of Gematria aren't evil, they're just scientists, seekers of the truth
Basement man and Beatrice are kinda evil though
Kaiser is evil
Average robot person in Kivotos is maybe evil
Dog and cat people are neutral/selfish

Sensei in volume F basically just says child is never evil, only misguided. And if they act out then it's the fault of the adults around them that lead them to their choices, it's not their fault. At least it's not their fault until they're an adult. You're too young to take responsibility for your actions yet, sensei exists to take responsibility for them no matter what they did, they have infinite chnaces
