Where it gets muddy is Assisted suicide.
And when and who get to decide when the end will come. e.g. teenager who is being bullied goes to the doctor and get a lethal dose and by law they have to assist or the 97 year old cancer victim who has just had enough. Someone who is in a vegetative state aka Terri Schiavo whose family is spit or a family is all ready for the end aka Craig Colby Ewert of the "Right to Die?" documentary who travelled to where it was legal Switzerland from Britain and carried it out with doctors help as he was unable due to degenerative motor neuron disease.
I am for it but there needs to be some serious check and balances for it with a independent medical body who give option on if death is the only option Or they should set up Suicide_booth to solve a lot of problems for both them and the people around them.
