I don't have the right to intervene by force in the face of a genuine sustained desire to die rather than admit to failure. I do, however, have the right to express my opinion that such an action is a grave mistake. As evidence backing my opinion: how often does someone say "oh that time a few years ago when I was feeling suicidally depressed but I finally gritted my teeth and admitted to failure, I wish I had gone ahead and killed myself instead"? Not very!
Nobody asked to be born and plenty of people would rather die than admit to failure.
