Daniel Kaluuya's character is a hitman, and he is a deeply disturbing one. He is often the most violent when you least expect it
Two men are unexpectedly shot in the head with blood mists, blood then pools beneath their heads.
A paralytic man gets repeatedly stabbed in the back, legs and hand, by a man. He then crawls out of the wheelchair with his leg covered in blood, as the other man throws away his wheelchair. This is clearly a torture scene, and is hard to watch because a handicapped man is getting abused. Some blood is seen on the floor
A mother slaps her daughter on the face, two women slap each other on the face, and a man slaps a woman on the face.
Three women break in a house, as one of them has a security guard held on gunpoint. The guard is then tasered. We then see a man pointing a gun at the women, as he shoots at one woman, and another woman shoots at him (he dies). Blood is present from a woman's wound, along from the man.
Three men are seen carrying a man who has been wounded from a gunshot, we see his bloody torso and blood coming out of his mouth, the men then die in an explosion.
A woman has a black eye. It is implied that her husband is abusive
Several gangsters enter a room. We hear them roughing up a man and possibly beating him to death. This is offscreen while a character sits and watches TV while this happens.
While several swat team members shoot up a van, the driver is shot in the head, we see some blood spurt from his face.
The overall tone of the movie makes the violence seem more dark and brutal.
