Families should have the right to end a loved one's life. When some one is close to death or their suffering becomes too much to bear or another end of life circumstance, it should be up to the family to decide what should happen to the loved one if there is no DNR or other thing.
Families should not have the right to end a loved one's life. The reason is who knows how close the family really is. Maybe the family wants the person dead so they just sign off on it. It should be left only up to the person to make the decision.
