Minerva looked at the law and then looked into her book. "Professor, life can not be used in transfiguration, even though we can change things into some animals like we did with the walking stick to a snake, we can not bring someone who has died back to the living. This is something that would be morally wrong and if you follow many beliefs the soul of that person does not stay with the body. So if that person was to be brought back it would not be the same person, because the soul as already went somewhere else."
