This issue always sucks.
The Military does a great job in awareness but in a testosterone-filled force, there is sadly very little that can be done to prevent suicides. Mainly because of the stigma and consequences incurred after coming forward.
Institutionally, the DoD cannot recognize suicides, even in a combat zone. That would create a culture where pre-suicidals would know they would receive some level of glory/vindication after they are dead, arguably leading to a rise in suicides.
It’s sad but capt is right. Even though God doesn’t SEND anyone to hell, it’s pretty much impossible to encourage a person who has reached the point of absolute despair. Not even the glory of heaven can earn their trust in God.
None of us has ever reached the point of absolute despair. This is why we are still alive. Personally, I have come close on many occasions but never to the absolute point.
