Except that it's not. For some people in other parts of the world, it's actually a better option than facing the reality they are forced to deal with or for those born into only suffering. There's nothing areholish about it, even for people in first world countries. People's actions and mental processes are as much effected by their environment as they are their own brain. And for some people, their enviroment is for lack of a better term, "cruel." Suicide isn't as cut and dry as you make it out to be, much like everything else in the world. Everybody has their own set of challenges to overcome, their own problems to deal with. It's not a selfish thing because they don't realize what they're doing. To them, their life is meaningless because they believe x does not care about them, or they as people are worthless. Now, to me, it's only ever a selfish act when they know it would harm someone else. I had so many opportunities present themselves every single I woke up when I was depressed. A car going too fast down the street, a simple drop from a certain angle at the right height. But I realized that I had people around me that cared for me and that if I did ever take any of those options, my act would have been selfish, because I knew what the results would be for others. For some people, this isn't the case.
