Mike Tyson doesn't want to know how his little "angel" died.

The former heavyweight champ said "my first instinct was a lot of rage" after his 4-year-old daughter Exodus was killed in a freak accident.

"If I know, then there might be a blame for it," Tyson said Monday in an emotional interview on "The Oprah Winfrey Show." "If somebody's to blame for it, there will be a problem."

Tyson said he's tried to not dwell on the bizarre circumstances of Exodus' death last May and is focusing on making sure the rest of his brood is happy.

"I was so happy that I had the tools in life, you know, to not go in that direction," he told the talk show queen.

"Because I've been that direction. I know where that's gonna lead me. I know I'm not gonna win."

Exodus was strangled after her neck was caught in the cord of a treadmill in the exercise room of her mother's house in Phoenix. Her 7-year-old brother Miguel found her hanging from the power cable.

The 911 tapes revealed the girl's frantic mother, Sol Xochitl, told the emergency dispatcher, "My baby! She's choked!"

Xochitl also tried to revive the doomed child until the paramedics arrived and took over.

Phoenix police called the incident a "tragic accident."

Iron Mike, who married girlfriend Lakiha (Kiki) Spicer two weeks after the tragedy, said he doesn't blame anybody or harbor any anger against anyone about the death of Exodus. He called his family "my biggest asset."

The Brooklyn-born ex-boxer said his children are "the only thing that matters to me now."

Tyson, who at age 20 became the youngest heavyweight champion in boxing history, has spent a lifetime trying to learn to keep his terrible temper in check.
