How is being in jail starting to change Steve's perception of himself?

While Steve is in jail, his perception of himself begins to change. Being around violent criminals all day has forced Steve to develop a tough outward personality. Steve refuses to smile out of fear that he will be viewed as weak. Steve also begins to notice that he looks similar to many of the inmates. He begins to question whether he is actually different from them or not. Steve also begins to question his outlook on life in regards to his values and morals. Listening to the other inmates trying to justify their immoral actions has made Steve question his own innocence. He wonders if he is trying to trick himself into believing that he is actually innocent like the others. Steve also questions his mental stability. When he thinks about the possibility of spending the rest of his life in jail, Steve contemplates suicide because he doesn't think that he could last that long.
