This novel is about racial injustice, but it isn't about a perfect victim. Jones is not above mistakes. He does lose his temper at a woman and he intimidates her (not without cause, but still). In the end, when he is made to be the victim of false rape claims, he becomes angry and licentious, using his victimhood as license for violence against others. Luckily, he gets caught before he can execute his plan to murder the white racists who have afflicted him. So, no, he is not a saint, but that's the value of his character—that he is perfectly human.
Since the novel likens racism to warfare in the Jones's dreams, the implication is that Jones will struggle to be non-violent. In the end, he is so afflicted that he feels driven by fury and panic to commit a horrible act of violence, but he gets caught. What's his punishment? That he must now go be violent in WWII where black people are being treated like expendable forces.
The picture is that the society is pushing for Jones to be a villain the whole time, because of the racist assumptions that define his culture. Because he is constantly being treated like he is morally inferior, he is driven to states of madness where he becomes violent, but that doesn't even begin to treat the major complication of his life, which is his constant misrepresentation and disenfranchisement.
The story's main inciting incident is that he is literally disenfranchised from his rightful authority because he couldn't hold his temper when an insubordinate woman called him the n-word and ignored his authority. Instead of defending his authority and firing the woman for being racist, the company demotes Jones and leaves him frustrated. He is constantly being forced to fail, and then his failures are used as evidence against him of his supposed inferiority. It's no wonder he feels so frustrated by his life—he is truly the victim of systemic injustice.
