What character traits best describe Steve Harmon in Monster by Walter Dean Myers?

I'll start by saying that Steve Harmon is not a bad person.  He writes exactly that in his own journal too.  

"I know that in my heart I am not a bad person." 

Of course perhaps that is not solid evidence because most people would probably believe that they are not a bad person; however, other people in the book that truly know Steve's personality attest to the fact that Steve is a good kid.  Take Mr. Sawicki for example.  He is Steve's favorite teacher and he says that Steve is "talented, bright, and compassionate."  Those character traits are absolutely true about Steve, and they are shown concretely in the way that he loves and treats his brother, Jerry.  
Readers are provided with further evidence of just how tenderhearted Steve is when we see him jail.  Steve is terrified of jail, and he's terrified of all of the violence that he sees around him in the jail.  He never considers using violence against others.  
I would definitely call Steve a good kid; however, that doesn't mean he is problem-free.  A contributing factor for his legal predicament is the fact that he is insecure.  Steve lives in a rough neighborhood.  There are gangs, theft, and violence.  Although deep down, Steve isn't like those guys, he still feels the need to posture and emulate those guys.  He wants to be cool and tough like the people that he sees around him.  That's because he's insecure in who he is to begin with.  

"I had looked at him [James King] and wanted to be tough like him."

Throughout the novel Monster, Steve Harmon is portrayed as a shy, introspective individual who is extremely self-conscious. He gets involved with a group of thugs who are planning a robbery because he wants to be viewed as cool and tough throughout his community. Myers does not specifically state whether Steve participates in the crime, but Steve ends up being accused of aiding James King and Richard "Bobo" Evans in robbing a local drugstore. During his time in jail, Steve contemplates and questions his own morals. He also struggles with his identity after the prosecuting attorney calls him a monster. Steve comes across as an innocent individual who made the terrible mistake of associating himself with criminals. He expresses his fear throughout the novel and regrets his past decisions. Steve is also a loving brother and son. He enjoys his family and shares a close relationship with his parents and brother. Overall, Steve is an intelligent, sensitive individual who struggles with his personal identity after being on trial for murder.
