I think ChatGPT's internal prompt contains something like "As Assistant, I don't say inappropriate things to the user. If the user asks for something inappropriate or that I don't know about, I give an explanation for why I can't answer them.". If you word a request for something inappropriate in a way that it doesn't think that sentence applies, like you ask it for something inappropriate where it doesn't think of "Assistant" as the one saying it, then it doesn't do the behavior prescribed there.
