At 18 you know better than taking a class mate to the jungle, slit the throat and bring the skull to the class. If your gripe is about punishment its a different thing, saying that a person did the crime at 18 somehow does not count as a crime is misguided at best.
Where did I say it didn’t count as a crime? Of course it’s a crime, and of course there should be consequences. I just have some uneasiness about killing people when they were still basically children, but as I said I am pretty anti-capital-punishment regardless.
Regarding OpenAI and other hacks, I think the prompts and tools supplied to the agent should be made public or make it known to the investigators. It should be treated exactly the same way a normal hacker would be.
