I think the problem is there's much behind the scenes in terms of beliefs and judgments as per suicide.
For example, I saw (with horror) people during the 911 twin towers collapse jump from 80+ floors, I think 2 held hands. Everyone can grasp 'why'- either inevitably they knew they were trapped and going to die one way, or they believed so. As much as we can all relate to the fear of what's coming, no one condemns that. Oddly enough, to the extent I can say, I wouldn't jump, that would be my decision. So it's not just a question of fear, or the avoidance of suffering or an 'easy' way out. It's not easy, to struggle with it or to choose it. One might say succumb to it. I mean really, even if someone doesn't understand, can they not 'guesstimate' how bad it has to be for it to feel like the only option left? In fact, I literally read an article once where struggling with SI can actually lead to ptsd. I get that, because it is such a struggle with near death. But it's anything but 'easy', or selfish, it's frightening and horrifying. No one 'chooses' to get to that point.
When they speak of Euthenasia for the terminally ill or chronically ill, approximately two thirds+ are in favor. But everyday I care for many people in that position, and have cared for many family members, and I can say it's my experience the greatest suffering is emotional, more than physical. And when that's reduced, and with better pain managment, the rest is a lot more bearable, even enjoyable (yes, people are actually happy. Heck, in my family if people committed suicide because of the fear their 'illnesses' and the unknown produced half of my family wouldn't have been born). And yet, a proponent in my country for Euthenasia, he expressed what he feared about his deteriorating health (he was incorrect as what he 'feared' such as being 'carried around' actually couldn't happen). But needless to say, he died and the article read "Unfortunately he died a peaceful death in the arms of his loving wife.." (WTF? I get it- they meant without seeing Euthenasia legalized here yet, of course. ) But really, what 'are' they striving for, if 'that' is considered 'unfortunate'?
Similarly, today in my country they said 4 people have been denied access to the neighbouring country because they had health records that indicated a past suicide attempt, and that medical info was shared with the 'authorities' (police, border security). Now, I know I don't know the whole story, they say it is within their discretion to do so and perhaps there was a threat to thers(?), but they did say the people were horrified and mortifed, so I doubt they were a 'threat to national security' because of it. But that was the verdict. Who knows.
All my life, I've cared for other people. I dare say in most regards I am not selfish, or certainly try very hard not to be. I give and give and give, what I do have though it's not much, although sometimes least of all to those who deserve it most. But if others condemn people for feeling lousy, I can't imagine they'd find the patience or energy or strength to give as is necessary for long in the capacities of the work I do. Is it a moral defect, or crime, or selfish (for myself) to not be as strong as the person leveling judgment? To get, or to wish to get, the oak tree off my back and the backs of others? If so I guess I'm guilty.
