which means you bring (much) value to the world. So it would be a shame.
Maybe. But consider that in the experience of the individual in this case - forced to suffer to benefit others, even though they don't want to live on themselves. Is that fair, or is it cruel?
I don't see myself suiciding, because I am far too stubborn :D
People who kill themselves do so, it seems, because they genuinely believe the lives of their loved ones would be better off.
I can understand this position, and perhaps in some circumstances the family would be better off. It is like the "a child needs their father/mother" but that is not actually true, and the child could be far better off without them. Think about all those stories of abusive parents.
The other thing is, that everything is a learning experience and the most is learned in hard times. Kids lose their parents in a war or car crash, what is the difference?
