Bigger killed Mary accidentally, yet he soon convinces himself that what he did was no accident and that it was right. Discuss the reason he felt this way.

Bigger Vance understands that he lives in a racially constructed society; for him, the world is clearly separated into the domains of white people and black people. As he sees himself making inroads into white society through his relationship with Mary, Bigger confuses accommodation with resistance. He believes that he is acting against racial discrimination by placing himself in a situation that is not generally open to blacks. Although at first he is fully aware that killing Mary was an accident, he quickly begins to rationalize his actions.
Bigger’s desire to assert control is far greater than his ability to think up a logical plan of escape. The adrenaline rush stimulates him toward self-protection but only through escalating violence, as he pursues and deliberately kills Bessie.
