My Father-in-Law died a horrifying and undignified death, on a hospital bed in his living room while choking on his own pulmonary fluids, while my wife tried (in a futile manner) to save his life. It pains me to think he could have preserved some of his dignity if he had been allowed to dictate the time and manner of his death.
Instead, he was sent home to die when doctors at the hospital said "we can do no more to save you."
Yeah, that was brave.
I am sorry about your F-i-L...did he want to kill himself? Since your lovely wife tried to save his life she has true peace and love.
