Terry the point behind your argument is so simple and one I am astonished that millions of witnesses don't think of for themselves: How can life itself be less sacred than the SYMBOL of life? You respect blood because it is the symbol of sacred life. If blood can be used to preserve life, that is showing it the most respect you can show it.
And if you let someone die because you didn't use blood to save them, you are freaking bloodguilty! WTBTS, you are bloodguilty.You can never see the forest for the trees, can you?
