Hellroller

A boy and his mother are attacked by a gang; the mother is also raped, and dies, while the boy survives and grows up a wheelchair-bound cripple. Ridiculed his whole life as some kind of freak by the "normal" people around him, he grows, with his monster complex, to hate the snobby well-to-do who have made him feel abnormal. Eventually, he becomes the world's first wheelchair serial killer, and with the aid of a mad scientist, plots the destruction of mankind.
