If the son were a Natural Law Theorist, he would again probably be influenced by religion. Instead of looking for a directive from the text of God, he would consider what “ought to be” concerning human life and ending it. For example, he might believe according to god, humans are meant to die on their own as life is sacred and follows a natural process from birth to death and people should not interfere with this by robbing life before its come to it's natural end. If the son were an Act Utilitarian, he would be free to consider happiness in his decision and decide if euthanasia caused the most happiness and least unhappiness. An Act Utilitarian could reason his mother's suffering would end and the family would be relieved she is free from pain. A Rule Utilitarian would consider if euthanasia adheres to a rule on the subject, which is made for the most happiness and least unhappiness. Perhaps it would be benefit his mother and family the most to perform euthanasia, but overall it may be a bad choice because its against a rule that states ending human life is a difficult decision and should be taken
