I think a lot of people truly don't want to die, but their situation or circumstances force them into acts of desperation. Desperation combined with survival instinct is the perfect recipe for a failed attempt because they often don't rationally think about the method, process or risks involved which leads to a lack of preparation and subsequent failure. We know better than anyone else just how difficult it is to cross that line. For example, hanging. 1 in 25 people who attempt hanging will cross that line, but then that 1 person has a 70% chance of succeeding their death and a 30% chance that their anchor may break, ligature may snap or they may be found too soon. Reasons for failure are definitely case by case so some methods pose more risks than others, but I genuinely believe many people feel like they have no choice but they're afraid to die or often times it could be a cry for help, especially when under the influence of alcohol or another substance. The statistics are sad, but I hope most of the people who failed did so because they didn't truly want to die or weren't ready, and I hope they were able to find the right guidance or support to live better or find sources of happiness.
