If suicide were accepted, then people could get lethal injections at hospitals with organ harvest benefiting others and less botched suicide attempts?

No: In many instances of suicide, the organs are not usable due to trauma, illness, or exposure to toxins, anoxia, etc. So this is not a viable solution for "organ harvest." also, suicidal thoughts or attempts often come from mental illness, which can be treated. There are places allowing assisted suicide, but it requires thorough evaluation by at least 2 physicians & a competent patient.

TMI: The issue of physician-assisted suicide encompasses a host of moral, ethical, legal, medical, and religious issues. Regardless of one's views, i feel that people should address such questions from all of the aforementioned points of view. Too much can be said about this to include on this type of forum.
