I feel suicide is a mixed bag of nuts. Honestly, it could be either selfish or tragic. I'll list some stuff off here.

[list][*]If someone feels truly backed into the wall and so far at the end of their rope that they see nothing left in living, it is absolutely tragic. Overall, we as a species, community, so forth, we should be partially obligated to register these people in pain and provide them help in the form they need. No one should be in so much pain and misery to have to seek suicide. It is not entirely selfish that, in this instance when a person is allowed to fall this far. They can very likely have entirely valid reasons.[/*]
[*]If someone is in such a mental or physical state as that their quality of life is severely limited, it is not selfish. In this instance, the depriving someone of peace and leaving them in such a state is the selfish act because a person is unwilling to let go. I for one entirely support assisted suicides for such cases.[/*]
[*]There are numerous mental illnesses that will push people towards suicide. In no ways is this the person's fault nor the fault of those around them. In this instance, it is a driving mental imbalance that an individual has no control of. The fact that someone's symptoms would have been so ignored and that they were either too scared due to social stigma or unaware to seek professional psychological attention is sad to see and is in no way selfish.[/*]
[*]In so many ways, parts of our cultures seem to have a dark infatuation, admiration or even obsession with suicide. It glorifies this act or puts it out there as something that is not wrong, that is a very valid exit to miniscule problems. This implants the idea in the heads of the impressionable and when something actually happens that would otherwise be unimportant and pass, a single moment of irrationality in anger or sadness can end a life forever. In this moment, I see two instances... This is selfish, and it is tragic. For a person to leap to that decision over something petty is wrong and puts others in far more misery than what drove the action.[/*]
[*]Half-hearted attempts and threats are entirely selfish. They come across more as a cry for help. If you're going to kill yourself, chances are... you know how to do it right. There is enough exposure, at least in American culture, that you're bound to know how...[/*]
[*]Suicide notes seem like another selfish part, at least, sometimes. Those writing a letter blaming those in there life... That's fucked up. That's selfish. However, those with extenuating circumstances, explaining the decision they were driven to is not so very selfish. In some ways it could provide closure and ease the loss if people are not blaming themselves.[/*]
[*]Again, I will point out culture. So many times, at least with adolescents, teenagers and young adults, it has become a norm to state at someone to go kill yourself and insults that demoralize and make a person feel alienated, worthless and worse. These comments are going to affect someone over time. Give it long enough, it will push someone to their limit and that one last direction to end their own life can be what pushes them over the edge. This has become a very real problem, and is not selfish in any regards. This person in all rights is a victim.[/*][/list]

I know that all jumps around a little, but I hope it clarifies my thoughts on the matter. There are those being selfish... Truly, I know there are. There are a lot of circumstances in which it is tragic, though... and even still some where, while it may be sad to know, is an act of mercy/compassion or even a more peaceful end.
