Deception is a human quality but it is not true for all. Some people, in their greed, end up hurting or cheating people who help them. But there are others, like the convict, who learn from their mistakes and regret them, especially after the Bishop supported him by saying that he himself had given the candlesticks to the convict as a gift. Judging all humans based on a single incident is unfair. There are many people in this world who return the good deeds done to them. Humans have different reactions to the same situation and they will not all react similarly to the same situation.
