They have not done tests to determine if she is brain dead. There is no way the video I saw was that of a brain dead person.
I do not pretend to know when the soul goes to God but my faith tells me that her soul is still with her.
Let's say that you are correct about the "killing" someone theory. Do you not also agree that the soul's release from the body could be one of the most wonderful experiences anyone ever faces. Is it right that her soul, if still with her, should be allowed to suffer and not be one with God again?
