Humans behave strangely when we encounter suicide. First, we claim that suicide is never necessary, that whatever ails a suicidal person can be remedied without the taking of one's life. While this is certainly true in many (perhaps most) cases, there must certainly be hypothetical situations where suicide is the best solution. I think that the concrete position of "never necessary" has been adopted as a mechanism to cause a suicidal person to reconsider their desire to die, but it seems that it is also commonly accepted by non-suicidal persons. This social position likely causes the suicidal individual to feel further marginalized, as they are told that "normal" people never consider suicide to be acceptable, while their own feelings dictate that it is in fact a practical solution to their problems.
Second, after a suicide has taken place, the victim(?)'s friends and family feel devastated with sorrow, and perhaps some amount of shame (likely due to the implication that their deceased loved one was abnormal for committing suicide). This is then followed by guilt, as the friends and family blame themselves for not noticing the signs and signals, and for not being able to prevent the suicide. These emotions are understandable, but I think that they miss a very important point. Specifically, the perspective of the suicidal person. Now I am making generalizations here, but let's consider the common thought processes that lead to suicide. From the perspective of the suicidal person, we have pain that won't heal, problems that cannot be solved, feelings of worthlessness that drive guilt and regret, and a lack of satisfaction with life in general. We are instructed that a suicidal person often transitions from intense unhappiness to a state of contentment once they have formulated a suicide plan which they intend to carry out. This indicates that these carefully planned suicides (as opposed to spur-of-the-moment, unplanned suicides) represent, through the eyes of the suicidal person, a solution to their suffering. I would imagine that for the persons who truly wish to die, (rather than the "cry for help" halfhearted attempts) the final moments of life are marked by a feeling of peacefulness.
Now unless you believe in an afterlife in which a person is punished for taking their own life, this seems like it would be a relief for a loved one, to know that whatever torments that drove the person to suicide are now at an end. I would hate to lose a loved one to suicide, but that is ultimately a selfish desire, if the alternative is a miserable and unhappy existence for the suicidal person. Now I am absolutely not stating that suicide is a good solution, or that a suicidal person can not or should not be treated. I am only pointing out that after the fact, once a loved one has taken their life, our grief should be tempered with the knowledge that our loved one's suffering is ended.
One more note on the bizarre (in my opinion) stance we take on suicide. If, as a society, we believe that the desire to end one's existence is somehow faulty, that it is a symptom of a problem with the brain, then an understanding of natural selection would lead us to the conclusion that every suicide brings our species closer to purging suicidal behavior from our genes. Now I know how that sounds, but I will not abstain from following a line of reasoning just because it might hurt some people's feelings. If suicide is really such a tragedy, then we should try to prevent it by treating the causes. Maybe treat one another as valuable individuals, unique in all the universe and through all time, past and future. Love your neighbor as yourself, or something to that effect. Oh yeah, and if you drink and drive, or text and drive, or facebook and drive, then you have no ground to stand on when discussing the value of life, death, or eternity.
Note: This has been on my mind recently because two childhood friends of mine took their lives in the last few years.
