Bridge jumpers are a pretty interesting phenomenon. In some areas there will be two bridges with equal suicide potential yet people will overwhelmingly gravitate towards one over the other and if a barrier is placed at the preferred location most people wont be bothered to walk the 1mile to the other nearby bridge.
most people who kill themselves are well, pussies. Based on what? Life in modern society is hardly challenging. Even if you're completely useless all you need to do is commit some petty crime and get thrown in jail and you wont have to worry about food or shelter.
What does the average person contribute to society? Not much. A large portion of low skilled work could probably be replaced by software at this point. Besides, the largest population demographic for suicide is eldery white men 75+ years old. What are they missing out on? What is society missing out on? Not much.
Life can lack fulfillment and be dreary for that sheer reason. For some people who do not have the capability to perceive true wisdom and wonder, life becomes difficult. As far as suicide, it could only be considered somewhat honorable in a context of altruism. The Japanese samurai, Shaolin warrior-monk, or German knight, or Saracen ghazi who restored his honor through a type of suicide often did so to protect his fellows and family. Rivals could have mercy and adopt the family into their own system, preserving the honor of the family instead of them becoming disgraced. There was no desire for pity, and these lofty deeds are seen in good people in the modern world who die jumping on grenades, storming machine gun nests, or destroying the fortifications of the enemy.
For the modern, suicide can be related to the ego and the self. While seeking the death of the self in the only way they know, they cling to aggrandizement of it in a gruesome moment. Not knowing of a "way", they discard their body without knowing the fate they condemn themselves to.
