Why finish him off, if she knows he is going to die anyway? She took her revenge on him for everything he's done, and most importantly, Mordred's death. Morgana couldn't have known another weapon like the one she gave Mordred existed, or that any other man would have such knowledge as hers(in fact, she was right, Kilgharrah told Merlin about creating such a sword). Shame. Merlin "killed" the last Priestess(not that she can die anyway), and with her the chances of bringing back magic to the land. This way, all three of them, Merlin, Arthur and Morgana, failed in their destinies.
