Disgraced financier Bernie Madoff has told an interviewer he has terrible remorse and horrible nightmares over his epic fraud but also said he feels happier in prison than he's felt in 20 years.

Barbara Walters told ABC's "Good Morning America" Thursday that she interviewed Madoff for two hours at the prison in Butner, N.C., where he's serving a 150-year sentence. No cameras were allowed in the prison.

Walters said Madoff told her he thought about suicide before being sent to prison. But since he's been there, he no longer thinks about it.

His comments come ahead of his wife's appearance on Sunday's edition of CBS' "60 Minutes." Ruth Madoff said in excerpts that they tried to kill themselves after he admitted stealing billions of dollars in the largest Ponzi scheme in history.

Walters quoted Madoff as saying: "I feel safer here [in prison] than outside. I have people to talk to, no decisions to make. I know I will die in prison. I lived the last 20 years of my life in fear. Now, I have no fear because I'm no longer in control."

She also said he told her he understands why his onetime clients hate him, and that the average person thinks he "robbed widows and orphans." But he also told her, "I made wealthy people wealthier."

The couple's son Andrew Madoff also will talk about his experience.

Another son, Mark Madoff, hanged himself by a dog leash last year on the anniversary of his father's arrest. Like his parents, he had swallowed a batch of sleeping pills in a failed suicide attempt 14 months earlier, according to his widow's new book, "The End of Normal: A Wife's Anguish, A Widow's New Life."

Madoff, who's in his 70s, ran his scheme for at least two decades, using his investment advisory service to cheat individuals, charities, celebrities and institutional investors.
