Actually, yeah, an autistic kid would totally care about global conspiracies. I started off obsessed with UFO's and cryptids when I was like 7, that led into Project Bluebook and such, and 20-ish years later I'm here.
3 injections a week for years on end. Immunotherapy. I have pretty much no doubt that affected my CNS.
I like how you framed it, though. It's way cooler being a backfired experiment of evil than just a defective.
And shit, I believe in souls anyway so it's not really like they can corrupt that with an injection.
