This is a very delicate subject. Once a person has committed suicide, there's no coming back (not as yet as far as I know at any rate).
Suicide needs a measure of control. The type of suicide that should be discouraged are those carried out because the suicidee feels life has failed them. Quite often, this is just a matter of perspective. Mental conditions can also make people feel suicidal. But these people can be helped as well. Although, suicide should still be an option open to them.
Suicide can leave the remaining people devastated as often, suicide is committed without discussing it with others first. This is the important issue. Discussion. In a lot of cases there are alternative and beter options. Occasionally, suicide is the best option.
What we don't want are suicides carried out in despair, using grotesque methods. Clearing up this kind of mess can leave a psychological scar.
A more considered policy is required for euthanasia or suicide. A system that would keep it personal and private, providing discussion and support, with practical options. The final decision should remain with the individual suicidee.
