People write these things because on a message board, other human beings are just an abstraction. Please, though, try to remember that to family and friends and even acquaintances, victims of suicide are not abstractions. I don't know James Dolan, but I know other well-known people in the industry who've died, and their families and friends did not take comfort in this kind of fantasizing. Rather, it was deeply upsetting to them.
It is, at least on face value. However gathering enough evidence to show some relationship or cause... that's a whole different ballgame that we probably won't get to ever watch.
