Even though he went in to the drugstore, looked around, and went out as he was expected to by Bobo and James King. Steve thinks that he is not really guilty of a crime. Why does he think this? What does this tell us about his personality?

I suppose being a "lookout" might not seem as severe as taking a weapon and actively robbing the store. Steve saw his role as passive in an otherwise violent stick-up. Steve does not understand that he was a big part (logistically) of the crime. This tells us that Steve does not think past superficial ideas about violence, crime and victims. He does not see that the seriousness of abetting a crime nor does he consider how the consequences of his actions had lead to murder.
