I too feel very deeply for George and his loss. He is a hell of a man IMHO. It is quite a feat to singlehand a 42 footer under ideal conditions.
No second guessing here, I was not there either and have never had to deal with his situation. If we sail long enough our turn will come, through lack of perfection, illness, weather, system failures, or some combination of those.
Walk a mile in my shoes comes to mind. And when my time comes, and it will, I know George and Gringo will come to mind.
