I am a philosopher with opinion of opposing euthanasia, because I define euthanasia as the same meaning of suicide, escaping from living. Choosing euthanasia is escaping from death because they can’t stand enduring pain or exposing their shameful sight. This is no other than a suicide. For any reasons, a society mustn’t affirmative suicide.
And, I don’t think the right of self-determination covers choosing death of their will.
Our existences are connected to other people around us, so you can’t decide your destination of life at your own discretion.
