You can add me to the list of those with concerns about assisted dying. My relative has downs syndrome, they are also autistic and have had times in hospital where we have been told they would not survive. Due to strong advocacy from us, they've then been transferred to a team who have done everything to keep them alive. They still have good and bad days, but overall have a wonderful quality of life.
Without this advocacy, and with assisted dying on the table, I believe that others in their position would not be here. The cheapest, and easiest option would have be to assist with dying in my d relatives case, and I don't have enough trust in people (human nature being what it is), for them to avoid the easy option of assisted dying for someone vulnerable with a serious, but temporary condition.
