David Reed's Blood On The Altar estimates 1,500 a year die from lack of transfusions or about 3 a day planet-wide. That's about 1 in 4,000. Even 1 unnecessary death is one too many. Contrast Mt 7 especially verse 12 and 1 Sa 14:32-35 saying Saul's army ate unBLED meat to not starve to death then Saul just made an altar of contrition, no verses showing God did not forgive the men from acting out of dire emergency. Mt 7 says David and his men ate temple bread but were forgiven because of the need to stay alive.
