New Moon is all about choices. Edward decides to leave Bella, despite the love they share for each other. Bella chooses to act recklessly and break the promise she made to Edward to keep herself safe. Each choice the character makes is followed by a consequence. After leaving Bella, Edward must live with the heartache and longing for his one true love. By putting herself in danger, Bella must endure the physical injuries her irresponsible actions brought upon her. New Moon also portrays how circumstances can sometimes dictate a persons life. We do not always get to choose.
An example in the Twiight series is Edward Cullen…he did not choose to live his life as a vampire, this choice was made for him and he was merely left to handle the consequences of that life. Both Edward and Jacob were not able to choose the fate of their supernatural abilities, but the two have the choice to either act on their animalistic natures or exhibit a large sense of self control and act on their human instincts behalf.
