Gwen
Gwen knew three things for sure, all of which she learned at aged eight: (1) she was ugly, (2) the only person she could depend on to defend her was herself, and (3) the only way to defend herself from bullies was through merciless confrontation.
Gwen lived her life according to those facts. Her resentments grew with each real and perceived unfairness and resulted in increasingly violent retribution, culminating with the loss of her only child. She was determined to get revenge. She lived for it.
During this time, however, she does find some good in her life and in her soul, and for a time, the good and the evil comingle inside her until, one day, she encounters someone as desperate as she is. Which part of her will win out then? The good or the evil?
