Chapter one of Walter Dean Myers' Monster introduces Steve Harmon's internal conflict regarding being in jail and facing a murder trial. One of the first times the reader "sees" how Steve is not one who would be involved in a robbery or murder is where his lawyer, O'Brien, states that her intent is to show the jury that he does not fit the "criminal profile."
In chapter two, Steve illustrates that he is unlike the others in jail through making contrasts between himself and the other prisoners. In chapter four, Steve mentions that he has a good heart (good hearted people do not commit murders or robberies). Chapter six offers more of Steve trying to separate himself from the other prisoners. Unfortunately, Steve is beginning to realize that he looks exactly like the others. In chapter seven, Steve's diary recalls much of his life now and before his arrest. At one point, he recalls that King had actually called him too "lame" to be involved in the robbery (which speaks to his character being unlike those who would be involved in a robbery or murder).
Throughout the novel, Steve continues to learn in what ways he is different from the inmates. He continually mentions the language and behaviors of the prisoners. This illustrates the fact that Steve has no clue how a criminal acts or speaks.
