My research reveals that non-theists have no serious nor attractive arguments against suicide. Traditionally, Buddhism does not view death as a bad thing or even as an ending. Rather, death is a transition from one stage of life to another. Because of this, suicide was not condemned, as long as that person had prepared his state of mind towards it. A key factor to this is that a person is in full control of his or her life choices and when suicide is prohibited, it means that a person is deprived of the final act of taking responsibility for his or her own life.
Suicide is a disturbing problem all over the world.
It is difficult for us to understand why such a country and its developed ally, Japan, relish suicide whenever economic misfortunes strike. Probably, because human life to them is secondary to wealth. There is no honour in poverty. Roughly, one person out of 100 attempts suicide during their life. Men have the questionable honour of being better at suicide than women.
