No, your grandfather was not a coward. I might choose the same at 84 if I had the same situation. I am strongly in support of legalizing assisted suicide for terminal or untreatable individuals, on the grounds that we are all autonomous and should have that right.
That said, I feel very differently when young people make that choice. Maybe I shouldn’t, I hold individual autonomy very highly in my personal value system. But with autonomy comes responsibility to those around us, especially those who love us. And that changes things. I have lots of anger and pain about the people in my life who have chosen suicide, and I have every right to that anger.
All that said, I should probably stop participating in this thread as it is about someone I don’t know. I feel for his family and wish them the best. I’m sorry Mark for expressing my own views about an event that is tragic for you, it was out of line.
