In my opinion, the question is quite clear. And based on the question, I would distinguish between suicide and self-sacrifice.
One thing is when a person wants to change something in this world, they have a goal that could potentially be approved by their like-minded people. And they are ready to pay a high price for this goal, such as their life. (This includes spies, astronauts, religious fanatics, but not schizophrenics, blackmailers, and other mentally ill people).
Another thing is when (as stated in the poll) everything is bad, and the person, on the contrary, does not see a goal ahead and, due to the lack of a goal, does not want to live.
In general, you understand, here there is a goal – there, there isn’t.
