Well when people consider suicide, that means they have felt utter despair and depression.
And if that happens, it would likely suggest that the suicidal ones have fallen under the belief
that their friends and family would not care if they died, or may even be better off. When people
being to feel like a burden to everyone and feel like they suck at everything due to pressure by
society, failures in the modern world, and constant insults from others, they tend to lose sight
very quickly of the good and those that care. So perhaps it is selfish to some extent in that they
only care about getting rid of their own pain, but really, often the people in that level of pain
might think that they're only being a pain to others themselves and believe they are doing the world
a great favor.
