After spike gives into greed, he becomes a vicious beast again. He attacks Ponyville and many ponies get hurt in the process. The second time he attacks, there are even more problems. Rarity is sent to slay him. Once she does however, she immediately regrets it.

I added some new things after taking this story down, just as suggested by, "toshibafox," I made this Rarity's fault which I might just elaborate upon in a sequel.
