Carson Fender aka Agent Zero from The Codename Conspiracy

because I love him

He's a child operative for a secret government spy agency. He has let loose fainting goats into his school as a distraction multiple times. He starts out a silly prankster who also gouges out someone's eyes with his thumbs in the same book (but we don't talk about that). He doesn't choose the lesser evil, but instead makes his own, morally correct side. He's definitely traumatised. He's not very good at his job and ends up unintentionally helping the villain three books in a row, but in the third one he uses this against the villain and betrays both the villain (who he was temporarily working with) and the 'good guys' who treat him like an asset and not a person. He sneaks into his teacher's super secret storage closet and finds earwax sculptures of boy band members instead of the incriminating evidence he was looking for. He eats paper several times throughout the series.
