Violence is everywhere in Kaffir Boy. Mark is the victim of police violence, the victim of violence perpetrated by his father, and then the victim of violence when he tries to leave a gang that he joined as a young boy. The violence he witnesses makes life seem worthless and pointless. Mark almost commits suicide one day when he's ten years old, and has come to the conclusion that life is not worth all the violence that comes along with it. Mark makes it through his brief suicidal period because of his mother's love, and his love for his little sisters. But the role of violence in his life isn't over. For a short period, Mark participates in violence, such as during the Soweto riots of 1976. Eventually, he realizes he doesn't have a stomach for that kind of life. When he decides not to be a tsotsi (gangster), his mother is relieved, and tells him he's chosen the more difficult, but correct, path.
