I wouldn't I'll just put him with a therapist

He would have offense level 43 at the sixth warning which would have life imprisonment

Force him to become a high school teacher

At least 6 years in therapy

Apparently the O.W.C.A. in-universe would give him 10-20 years. In real life? He would either get life in prison or alternatively be put in a mental hospital because he clearly needs severe psychiatric help. I personally would rehabilitate him so that his genius could be used to build machines that can actually help people.

Years in therapy and talking to his brother.

I'd just sign him up for a therapist, just please give bro a break atp

I would sentence him to 24 months in prison with charges of kidnapping, multiple accounts of thievery and sabotage, animal cruelty, unlawful imprisonment, attempted citywide domination, mass brainwashing, impersonation, unethical experimentation, trespassing and God knows what else lol
