These cherry-picked suicide-completions, almost always feature young, visibly vibrant, attractive, intelligent and family-oriented individuals, and this of course gives the impression that almost everyone who intends to kill themsleves can be saved.
"Why would such a beautiful and successful person flush themselves down the drain of non-existence!?" It's outrage over the annihilation of the *aesthetic*, and the character traits of the individual, rather than thinking outside of the frames of the documentary, in order to understand and digest that there might be horrific sensory torture that lies beneath the surface.
They also tend to focus on a "social-defeat" model of suicidality: so think of divorce, social ostracization, losing socialeconomic status, getting fired, etcetera. They pick the lowest hanging fruit generally and gas them up as gods who were previously thought to be immortal, until they go on to complete a suicide. So the audience gets the idea that the "face" of suicide is usually a beautiful, young person, with a high intellect, and a successful application of that intellect, but they come to a false realization that the suicider just can't see the "full picture" like the audience can, which makes the audience believe that this suicide was incredibly impulsive and short-sighted. In reality though, social defeat is likely the tipping point for most people and not the cause of overwhelming sensory torture.
Rarely do they capture the scalding hot chains that mercilessly bind a person to a severe, complex chronic alien (physical or mental) illness, that has no clear etiology, no clear treatment and subpar management strategies. If they showed, say for example, someone with severe developmental deformities coupled with ghastly presentations of unconscionable chronic illness(es), then the perception of the audience is often congruent with the person's plea for a death with dignity.
Pious anti-euthanasia believers, i've noticed, often believe the world should revolve around their ideas and beliefs, and that violating these beliefs is somehow pulling the curtains up and exposing themselves to a reality they would refuse to subscribe to. These documentaries just give more fuel to their arguments that a life taken by one's own hands is *actually* criminal and every precaution -- including censorship, jailing, banning of substances, etc. -- should be taken to protect the individual from committing a crime against themselves.
