Your fate as a vampire is a bit of a mixed blessing for you. Sure you get to live for all eternity, but the havoc that your bloodlust creates is more than your soul (or morals) could possibly bear. So now you are doomed to spend eternity trying to escape the fate that has befallen you. Whether devouring rats or hunting elk, you will do whatever you can to avoid the dubious pleasure of the human flesh. But as much as you try to avoid your true nature, you know that a monster inside is struggling to escape. With practice and patients you may one day overcome your natural desire, but don't beat yourself up about the slip ups. It is your fate after all.
