In my AP English class in high school (1995) we had to read Native Son by Richard Wright.

The book is about a young black man that commits heinous crimes against two women yet Wright attempts to persuade the reader to feel sorry for him because of his economic and social plight. The acts of violence committed by this young man were brutal and Wright did not spare words describing them however he attempted to justify them.
I cannot fathom any reason, socioeconomic or sociopath, that would motivate someone to do what Milagro Cunningham did to this young girl. He is pure unadulterated evil and hell is too good for him. Every breath he draws is an insult to life and I pray his will be ended soon.
