Agassi, a Legend?

Eight time grand slam champion, Andre Agassi, admitted his recreational use of crystal meth, during his 1997 season, in his new autobiography. It is worth noting, his drug use is not performance enhancing, rather, recreational. Agassi, widely acknowledged as an all-time tennis legend, successful multi-millionaire, had everything to lose in admitting his usage of the drug. Or did he have nothing to lose? Agassi won a gold medal at the Atlanta Olympics of 1996. However, in late 1997, his ranking dropped to No. 141, one of the most severe drops in ranking any tennis pro has ever done- equivalent to playing in the "minor leagues" of tennis. It becomes obvious now, why, in 1997 Agassi's tennis game became so much worse, a side-effect of his drug use. By 1998, Agassi jumped back up to a top 10 ranking, making the single greatest increase in ATP ranking history. A year later he won the French open, completing a career Grand Slam, and finished 1999 ranked No. 1. After his use in 1997, Agassi salvaged his career, and recovered into the legend he was destined to become. Why, 12 years later, does Agassi admit to using the drug? I'm not able to think of a reasonable explanation for Agassi's admission.  He was not under persecution, or investigation. Is this his form of self-purification? Did he want to feel better about himself? This could have never been announced, and Agassi would go down in history as a tennis legend. Yet, he made a decision to tell everyone. His family, friends, fans, you and me. So how does our view of Agassi change? I would still say that he's pretty good at tennis.
