Your comments and questions are making me want to work on the continuation of this story arch. The next chapter would explain a lot of your questions! Sorry, no spoilers!
As snobby as that girl was, nobody deserves what that selfish boy did. She may not have chosen the other guy over him for the right reasons, but it was not only her right, he had no hope of finding any good woman with that attitude. And he resorted to doing the unthinkable. Sadly, I see to many people (men and women) go down the same dark path when they delude themselves into thinking they are owed anyone's love.
The allegorical aspect of this story is that lust, infatuation and, selfish ambition can disguise itself as love. Those vices turn a person into a monster!
Can't wait - hnnnng :)
(Oh - sorry for the almost-rhyme.)
