Laws regarding suicide don't exist to punish the offender. Laws regarding ANYTHING, in fact, do not exist to punish the defender, they exist to protect the people they affect, in this case, the individual considering suicide.
Plenty of people who consider suicide, or even attempt suicide, later regret their decisions. Impulse suicides DO happen, or at least impulse suicide attempts. People who want to kill themselves often feel alone and scared and don't know what to do. If given the opportunity to talk about how they feel with the people they care about, if given the opportunity to understand that other people are around who want to help them, those people may change their minds. They may realize they're not as alone as they thought. To claim that all suicides are not only premeditated, but also premeditated enough so as to assure there would not be regret, is absurd.
People need to learn that laws do not STOP actions, they dissuade people from doing those actions. People who really want to do something will do it, regardless of legislature. That's why there are criminals. People who really want to kill or to **** or to do illegal drugs or to commit suicide WILL do those things. People who have given enough time to considering suicide to decide that they really want to commit suicide will do so. Even if those people are stopped and given help and counseling, if they really want to commit suicide, and they still want to even with the help others have to offer, they will still do so.
Legislature to help people who can be helped and might decide they prefer life will not affect people who really, truly want to die. If counseling changes their minds, then they decided that they want to live instead. No one can decide for them. All the counseling in the world can't change the mind of someone who doesn't WANT to change their mind. No one can MAKE a person decide not to commit suicide.
Suicide is only a token crime, since dissuading suicide and offering help to people considering suicide is so important. Suicide is not punished.
@cF=), I think you're making definitions about what morality is that eventually circle around on themselves. Determination of what rights a person has is the determination of what they are and are not allowed to do, what they "should" and "should not" do, related to the majority's morality. Laws change because people change and times change, and majority morality changes, as well.
Morality is just a personal decision about right and wrong, and laws and customs reflect what the majority believes to be right or wrong. You want morality to mean "religious morality," but it doesn't. Morality is the only thing that influences legislature. What the majority believes to be right is legal, and what the majority believes to be wrong is illegal.
