We say that those how choose to die are sinners. but those how kill (in the name of God, or at war) are heroes.
I'd like to test that in a Foucault like fashion. Imagine that we would say that those how kill them selves are heroes! they came closer to God. they have the courage we lack. they are brave, taking the matters of life and death to there own hand.
we would build statues of them, praise them and so on...
try to see a world like that - would you choose to die in that sort of a society?
