If a spouse or loved one was declared brain dead then the person no longer lives because the brain is what makes the rest of the body function and live. If the brain is dead, the person is dead. The person can no longer see, reason, or think logically because they are now in an inert state of sleep which they cannot come back from. If my spouse or loved one was officially diagnosed brain dead by the doctors then I would ask the doctor to remove the medical equipment from my loved one’s body. If the individual is brain dead then all other organs will eventually shut down, once the brain is dead there is no hope for it. Also, I’m religious… specifically one of Jehovah Witness, I believe that when someone dies they are not in heaven or hell. Instead, they are at rest, in peace. In the future they will resurrect in a paradise where they will enjoy of youth and no sickness like so mention Revelation 21: 2-4 that says: “God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.”
The decision to remove the feeding tube should be the person who is closest to the person. For example: If it’s a child or adolescent then it should be the parents. If it’s an older man with wife and children then the wife should decide if yes or no to remove the feeding tube.
