I am not a bad pony.
I do not do the things I do because I am evil. I do things I do because I used to be loved, and I used to be inseparable to her. She was my everything when I was a filly, the mother I never had, and I imagined spending the rest of my life with me under her wing.
Then she abandoned me, stopped paying attention to me, teaching me new tricks, and spent her time with another filly, a "more promising student," and I was left out in the rain. She never knew how much it scarred me that day.
I do not do the things I do because I am evil.
I do the things I do to get her back.
