Maybe it's a tip for people who want to commit suicide, go educate yourself so that your first attempt is a successful attempt so that other don't have to live years after year with a person they will constantly fear about.
Also if you commit suicide don't jump in front of a train or a car or do it in such a way you put others in danger or years of psychological trauma.
And If your suicide atempt fail's like the guy I know who jumped in from of a train and lost his both legs, don't expect people to take care of you. or show you empathy....oh wait empathy does not exist.
And then finally to those psycho/sociopaths who use the threat of committing suicide as a manipulation tool, may you be accidentally successful someday.
Edit ; this is another perspective to look at it.
