But he did get away with it for some time. I would like to know about his pysche ie what caused him to do it.
Well, he needs the kudos of an audience, whether it's pupils in his charge or the general public, he's looking back to a time of particular fondness in his life when he was a naval cadet and wonders what trajectory his life would have taken had he not become a teacher. He's bitter that he didn't advance further in his chosen career. He likes the thrill of deceit, he's obviously going to be found out, but the risk was worth it since his feeling of diminishment since retirement and the fear of growing old has made him rather depressed, and this action gave him a temporary fillip.
Will that do you..
