I think, the punishment given to the convict was not justified. He was not a seasoned or habitual criminal. He had no money and had to steal for food for his ill wife. He was sentenced to ten years in the prison hulks. He should have been let off with a mild fine or a token punishment.
He is eager to reach Paris as it is abig city. He cannot be easily traced by the police in such a big city and would be able to lead a new life.
