At the risk of sounding crass and unfeeling (which I am NOT) the GB has been careless about peoples' for as long as they've been pretending to be "God's Spokesman." Before them Franz, Knorr, Rutherford and Russell were more interested in their own personal agendas than the health, safety and welfare of anyone else.
Why should you expect them to be any different now?
They're just doing what they've always been doing. This is only more of the same. Note that the GB members aren't going. No, they're safe in their "Watchtowers" where they'll be watching others take the risks while they take the credit.
Anyone noticing a pattern here?
