The most direct reason is the reshuffle of Shawshank prison. That is to say, because Andy successfully escaped from prison and reported to the warden and the captain of the prison guard, all the leaders of Shawshank prison changed their minds. The warden committed suicide, the captain of the prison guard was arrested, and many people were not shown. It must be implicated. Judging from the group of people Rhett faced in his third parole defense, Shawshank's account should be thorough.
In other words, primitive people may have a different understanding of redemption than the officials behind them. This gives Rhett a new chance, and gives him a chance of parole.
The new officials in Shawshank Prison need to show that they need to get rid of the old official style and establish a new reputation and make new achievements for the outside public. They are eager to restore public confidence in the government through some good performances. For those who have been domesticated and detained in Shawshank prison for decades, it is naturally not so harsh.
This was well reflected after Rhett went out. He works very well in the small supermarket and is also very serious. It can be seen from the manager's attitude towards him that everyone is actually very satisfied with Rhett. It can be said that these new officials bet on the right treasure. Of course, this is only temporary. Who told Rhett to escape directly across the border and no longer appear in their monitoring range?
In the first two conversations, Rhett's attitude was perfunctory. In the whole movie, Rhett's parole conversation appeared three times. The contents of the previous two conversations were almost identical, and his answer was the same, perfunctory, as if he had no hope for everything. Nor can people feel his true repentance and redemption. But the third conversation is different. Before the third conversation, he experienced the death of Bob, saw the warden who had been oppressing them dismount, and got used to the ethics of life and death in prison. After Andy escaped from prison, his view of hope changed completely.
Redemption of Rhett means that Andy in The Shawshank Redemption has fled and lived his own life abroad. At the same time, he also saved Shawshank prison for nearly 20 years, making Shawshank prison different and the people inside different. Rhett, in particular, represents almost everything in Shawshank prison. Andy left him hope before he left, telling him where he left something for him to discover.
This already means that Andy knows that Rhett will definitely fight for the opportunity to come out, and it also means that he believes that Rhett can find his own way of redemption. Rhett represents Shawshank's institutionalized but anti-institutionalized people, and represents those who have lost hope but rekindled hope. His parole, his crossing the border to find Andy, are the needs of the plot of this film and The Shawshank Redemption, so his parole is inevitable.
For a parole officer, there have been countless "I turned over a new leaf" and "I regret committing a crime" in my ears. Rhett's answer is that he feels depressed and miserable about the mistakes he made when he was young, helpless and sorry for his inability to make up for them, and frankly accepts his situation, which left a deep impression on the parole officer and made him hear it.
