His autobiography is fascinating and sad. There is no excuse for some of his crimes but you do understand him better when you think about how messed up you'd be if you grew up with a mom who had sex for money with men while you slept in the same bed. It was a highly traumatizing childhood you can never escape.
you have a young man in the unusual position of being both gladiator and emperor, "a sewage rat with delusions of grandeur", a ghetto kid with zero self-esteem and an ego borne of the knowledge that, in a fair fight, he could beat everyone on the planet to a pulp.
Overall my takeaway was Mike Tyson is much smarter (with a fascinating grasp of history and philosophy), but even more ****ed up than most people understand. He truly hates himself and probably always will.
