Mike Tyson: I don't believe in redemption

(CNN) - Former boxing champion Mike Tyson has been the baddest man on the planet, served time behind bars, did a cameo in a blockbuster comedy, and even starred in his own one-man show on Broadway.

Now 'Iron Mike Tyson' is an author, telling his life story with a bare-knuckle honesty that is both tragedy and comedy.

But Tyson isn't seeking redemption with his new book, "The Undisputed Truth."

"I don't believe in redemption. No one can redeem themselves. It's either they want to change their lifestyle or they don't," Tyson said in an interview with CNN's "The Lead with Jake Tapper."

"There's no such thing as we want to redeem ourselves. We don't forget what happened in the past," said Tyson.
