We need this in the US.
Suicide sucks, but let people make an informed decision, explain their rationale to their loved ones (if they want), and take the dignified way out. Having sat in a house, tasting the blood in the air from when my son-in-law took his life with a gun to end the pain of his cancer, I don't want anyone to have to go through that. It has been several years and our family still hasn't healed from that trauma - mostly because of the stigma, and my daughter's request that we just tell everyone he died peacefully in his sleep.
I would have much rather given him a hug, shook his hand and thank him for being such a wonderful presence in my life... and then know that his last moments on earth truly were peaceful, not violent and messy.
