In most cases, people simply don't know how bad it is or can't imagine it could be that bad or have no idea how to help, etc. It makes me crazy and I wish the world were better about such things. Yes, it took his death for people to "care", because his death was clear information about how very bad it was. People are still talking in part to try to figure out how to see it more clearly beforehand next time and not have to wait for such a clear signal. At least I hope that is part of the motive, for some people.
