Rii, I think you're wrong. It's that impulse to think of others that's stopped me from doing something terminally stupid.
If a person thinks of those around them, it will put their problems in some perspective. Take the focus off themselves and onto family and friends, and the world does look different.
I don't have a problem with someone refraining from suicide because they're worried about the effect it'll have on their family, or with someone attempting to convince them not to commit suicide upon that basis. In most cases - as you say - the impulse is temporary and
anything which makes the individual catch their breath long enough to discover that there's still cause to go on living is a good thing.
What I do have a problem with is the notion that in choosing to commit suicide, the person was acting selfishly. Coming
from the family it doesn't bother me so much, people express their grief in different ways and their behaviour would have to be extraordinary for me to cast judgement upon them under such circumstances.
It's when it comes - as it usually does - from folks not directly involved in the affair that I, err, 'object'. It reflects not only hubris in believing that one knows the suffering of another, and of the relationship(s) between the individual and his loved ones, but a cruel arrogance in assuming the right to cast judgement upon the deceased based upon such assumed knowledge, and cowardice in light of that individual's absence and inability to defend themselves against the charge. Worst, it demonstrates a callous disregard for the very essence of that individual as a human being, by implicitly suggesting that everything the he (or she) is should be subordinated to the interests of others, like a tool.
I'd like to think that - if the occasion arose - I would sacrifice my life for those of others. But I would fight to the death against the notion that anyone has the right to
expect that of me. And of course, dying for others is much easier than
living for others. The former requires merely a single, probably fleeting, act of will. The latter is endless. No one should be expected to carry that burden.
