Re: Sins
Whomst here is bringing up wealth? You pulled that out of your ass for some reason, even though I made no mention of it. I pointed out Japan because they are a non-religious country overall and they have high suicide rates. Their suicide rate can be attributed to a lot of things like their economy and its impact on the people, the phenomenon known as “hikkomori”](Why does Japan have such a high suicide rate? - BBC News), insane school pressures for children, among other things. None of which are religion.
So let me repeat again: Correlation = / = Causation
One cause for lower suicide rates in uber religious countries could be because suicide is a sin in Islam and Christianity which are the predominant religions in those countries which topped that list.
Purpose of life: Live life to the fullest until it is finally time to croak.
