Had he been a witness at the time of all those blood transfusions he recieved he would have been removed from the congregation and sentenced to die at the great battle of ARMAGEDDON. Likely many living today would never have come into existence- some of those probably JWs. Thankfully he saw fit to return the favor of giving back what sustained his own life.
Today if you're a pregnant JW and you happen to have the opposite blood type than your unborn child, it's alright under current doctrine to accept this antibody because the vaccine they created from his blood contains blood fractions! Give all thanksgiving and praise to Jah that you didnt get pregnant back when all products containing any amount of blood were banned! No doubt Watchtower/Slave/Jehovah would condemn this man who disrespects the sanctity of life by providing the blood necessary to save your baby.
Such hypocrisy.
