sorry i couldnt resist the wording

in all honesty i am not highly religious and am.. for lack of a better term agnostic
tho i do still stand by this saying in a different sense

the ability to exist or live.. be it a curse or a gift.. is given as to allow you to become a part of existence.. a part of life.. a part of the human race.. and to survive and allow life to continue existing
to throw away ur own life for the reasons of.. for lack of a better term.. weakness.. is to neglect one of the greatest of responsibilities if not the ultimate

in another sense:
the ability to think and make the choice of self destruction is a product of ur existence
you are contradicting not only your own thoughts but ur entire existence

so by suiciding you are not only being untrue to the world
but also to yourself and your own being
in this sense there is no justification or "right" for ending ur own existence
even from a selfish point of view

the only justification i can see at all is the "right" of "choice"
but even ur ability of choice is contradicted
