As everyone else said, the person is doing their best to lift everyone else up, while they are doing nothing but sinking. Some that are hurting can only hurt others, because they don't want to be alone, out of spite, etc. But that person decided to help out instead of drag down. Those are the kinds of people that make life worth living.
I would think, that I am proud of that person. Not for ending their life, but for living what they could of it, and using it to give others hope. Every second they were alive was not just time that simply "healed" them, but were little moments of patience that taught them to deal with the pain. However long they lived was time to be treasured, time to keep fighting, time to overcome the pain in the butt that life is most of the time. And thus, time to teach others how to use their time in a similar way.
Hypothetical or not, I truly hope that Harmful Heaven will touch on these topics. It could help out lots of people.
