> the fact that he killed himself would suggest he did not believe it was a fun little roleplay session
I'm not sure that's true. I wouldn't be surprised, in fact, if it suggested the opposite, it seems possibly even likely that someone who is suicidal is much, much more likely to seek out fantasies that would make their suicide into something more like this person may have.
there is a distinction to be made between role playing (in the fun/game sense e.g. D&D) and suffering psychosis
Distinction made by who, though? The BBC? The plaintiff in the lawsuit? Those are the only sides we have. You're just charging ahead with "This must be true because it makes me angry at the right people", and the rest of us are trying to claw you back to "dude this is spun nonsense and of course AI's will roleplay with you if you ask them to".
