QUESTION: Why would one vampire create another vampire? On the one hand, we know
the reason that Edward and the Cullens were transformed, and why the new born army and
Maria's army were established, and that a vampire could change someone who learns the secret. However, in a general sense, a new vampire would be competition for the existing vampire. Other than the specific instances I mentioned above, why would the transformation be done, and how would the existing vamp resist draining the person?
