After seeing friends and family struggle with severe injury / deformities and Alzheimer's / mental decline (cancer with grueling treatment as well) - I can as a currently happy and healthy person say that I would likely use some form of firearm to end my life. It's quick, hard to mess up and above all my right as a human being.
I generally dislike political spats regarding labor / "obligations" to society in general - but I think the most sacred right is the right to decide whether you contribute by living. Both capitalism and socialism demonize the idea of suicide because each needs some form of a worker and the pursuit of a certain constructed life to work properly. Something that I'll never understand and that I believe is more morally wrong is family deciding that someone should "get over" their own choice to no longer live. In my opinion nothing is more selfish and less respectful of what life should mean to an individual.
