I'd also say that suicide should be an accepted option to end one's life.
Currently, the opinion seems to stem from religion (God does not allow it, or in the secular version, it is not allowed because of the waste of potential) or medicine (suicidal intentions are always a sign of mental illness, which is wrong).
This is a modern view anyway, think about all those Romans who prefered to kill themselves instead of facing defeat, or samurai who killed themselves rather than facing shame. This was accepted and lauded, not shunned.
I believe that life belongs to the person that lives it. If the person thinks it not worthwile, or imagines life after death to be BETTER, why shouldn't he commit suicide, if he has thought it through and is not acting rashly?
A concept corresponding to abortion appeals to me: Mandatory counseling, and then you can go ahead with it, no hassle.
