I have a friend who believes that it is genuinely possible for a life to be net-negative expected utility, making suicide the right answer sometimes, and that he either is or may eventually be in such a scenario.

He is too afraid to talk to anyone about this except under an online pseudonym, because he is too afraid that if he actually talked to a psychiatrist about this, he would be immediately and involuntarily hospitalized for suicide risk.

He is terrified that he will soon not have even the option to commit suicide - even if it is truly better than continuing to face a life not worth living - because of precisely this kind of well-meaning ubiquitous monitoring and predictive warning. I'm really worried that he might just try and kill himself pre-emptively while he thinks he still has a chance.
