This is uncharitable and uncalled for, given that the poor man did nothing wrong, is dead, and leaves behind a grieving family. The man DID go to a hospital, which appears not to have treated him correctly. Are you calling him a “fool” for not having used a “cheap first aid kit” instead of going to a hospital?
Two people close to me were bitten by rattle snakes and were fortunate enough to be close to top-flight hospitals that were able to treat or airlift them to hospitals that could treat them for rattlesnake bites within the time period when their lives could be saved. Also fortunately, neither of them were allergic to anti-venom, which would have left amputation as the only option for saving their lives.
It’s a common risk in many areas of the US. Edumacation starting with youngin’s is still a good idea, as is carrying a suitable first aid kit when outside. Be Prepared. Your life depends on it.
