You misunderstand the intended purpose of the article. You're not supposed to see these anecdotes of prison experiences and morals and interpret them as lessons that you should have learned and didn't. The point is to spread understanding, to offer a glimpse into the minds of those who have experienced prison, especially those whose previous lives were so different from life behind bars. You're right, directly confronting the perpetrator rather than seeking help from the authorities is often inappropriate in "normal life", but the point is that prison changes people. Before prison, the convict would choose to respond to a conflict as would you and I you and I, and believed that was "correct". But prison changed him in that respect so completely that he recognizes that he changed and fully believes that it's for the better.
