A hypothetical question..
It is easy to make decisions for oneself, or for children who come under your jurisdiction, but suppose that your consent were to be requested for emergency treatment involving blood, to a person that is a diehard Witness?
I am talking of a person that has spent her entire life in the Borg and believes that blood transfusions are a sure pathway to contract aids or something else nasty. If she were conscious I am not convinced that she would accept even the treatments with blood fractions, that they do allow. If I were to consent to a transfusion then she would truly feel violated and angry for a very long time. I would never be forgiven.
I do support the concept of an adults right to chose, and make decisions regarding their own body, but then again that person has only entertained information from the WTS regarding the subject, so they are unaware of the full picture .
The choice is to either respect her conscience, or to give her the best opportunity for survival? Is it right to withold potentially lifesaving treatment from a person who would not have accepted it herself?
