Replying...
Intro. Thomas Hewitt, the person who would transform into the angry beast famous as Leatherface, was once an infant with a curse. He has a disease, which was slowly eating away at the flesh of his face, disfiguring him. This led him to be a social outcast, and with the sadistic nature of his family, this has slowly turned him into a monster. This got even worse once the place where Tommy worked (a slaughterhouse) was closed.
