Ben Carson admitted to his violent past during an interview on NBC's "Meet the Press," when he was criticized by fellow GOP candidate, Donald Trump for having "low energy." Carson recently beat Trump in the latest Iowa poll, according to a previous report by HNGN.

"Ben Carson is super low energy, right? He's super low," Trump said regarding Carson's demeanor, according to CNN. "Super low energy. We need tremendous energy. We need tremendous energy."

During the interview, Carson clarified his relaxed attitude.

"I do have a tendency to be relaxed," he said, according to NBC. "I wasn't always like that. There was a time when I was, you know, very volatile. But, you know, I changed."

This violent time was when he was growing up in Detroit, Mich. which he also detailed in his book, "Gifted Hands."

"As a teenager. I would go after people with rocks, and bricks, and baseball bats and hammers. And, of course, many people know the story when I was 14 and I tried to stab someone. And, you know, fortunately, you know, my life has been changed. And I'm a very different person now," Carson added.

Now, Carson is a part of the Seventh Day Adventist Church. He used to serve as an elder in the church and a Sabbath school teacher, but clarified that the beliefs of the church are not the most important factors in a religion.

"I spend just as much time in non-Seventh-day Adventist churches because I'm not convinced that the denomination is the most important thing," he said, according to Religion News. "I think it's the relationship with God that's most important."
