My brother in law, who has Lewy body dementia, along with other serious health issues, has registered for medical assistance in dying. Since he may not be able to give consent when the time comes, he has a contract with a doctor which defines when he no longer wants to continue to live. The doctor can give permission for his euthanasia when the time comes.
In your mind, is he murdering himself?
Modern medicine can keep people alive with machines for decades. I think that is cruel and wrong.
When my son was in and out of icu for seven months, there was an eighty something year old woman in a coma in icu who was there before he arrived and still there after he died. Her family would not let her go.
