What happens to the lawyer in the bet at the end of the story?

At the end of Anton Chekhov's short story "The Bet," the lawyer, having spent fifteen years in solitary confinement, emerges disillusioned and weary. He renounces the two million rubles he would have received, realizing that life and freedom are more valuable than wealth. His experience has led him to reject materialism, highlighting the futility of his previous ambition. This dramatic conclusion underscores the themes of isolation, the nature of happiness, and the value of human connection.
