I think suicide is welcomed when you harbor a convoluted idea that the universe is against you, that probably you are the worst mistake to happen all because an endeavor you sought to achieve did not pan out.
Depression also propels one to think suicide. How can one be free from this? Ain't easy, won't lie but it's better to talk to someone whom you can trust about it when you feel the walls are closing in on you than just giving in and adding to the number of suicide casualties in the world.
I hope that you do not think the universe is out to get you.
I for one admire your name choice and I am on your side.
Back to question. Sometimes heroes are certain they will die and they do die but save people by dying.
Technically that is suicide but I wont count that and I am sure many here would not.
First Wonder Woman Chris Pine crashed a plane knowing he would certainly die yet it would save many people (never mind the sequel)
Many people have taken bullets knowing they would die but that it might save someone else.
Not counting those as suicide.
But on the viewpoint of the world tradecenter plane attacks. A non muslem would think it was a suicidal act.
Some moslems would think it is a wonderful act of faithfulness. ( That is for you to ponder badecker)
I will leave all of the above out of the op’s question.
The Standard “my life sucks I am killing myself suicide” = dumb as fuck. Huge risk factors virtually no upside. So many downsides.
How to stop it , likely impossible to stop that type of suicidal pattern.
I had a friend that drank himself to death about ten years after his mom had hung herself in the garage.
Very sad I could not get him to go to alcohol anyonmus he died from booze.
