"We all agree that we don't condone violence," Moore said in an interview on Monday. "We've become angry with each other, we've threatened each other and gone to the edge. But at the end of the day, we know there's a line. If there are no consequences, then where does it end?"
Williams surrendered last week to authorities and was charged with a misdemeanor charge of battery for the fight, which was televised as part of the Bravo show's reunion special on Sunday.
Williams and Moore have had friction during the entire season, so it wasn't surprising that the two began to argue and trade ugly accusations during the reunion special. But then things got physical. Both women stood up and Williams grabbed Moore's hair, pulling her down and dragging her across the floor. On the show, Williams said she "blacked out" but was regretful about the fight.
"I think Porsha was in a position to provoke me," Moore said on Monday.
Moore said Williams should have been better prepared for the reunion show, which typically brings up past feuds and confrontations between cast members from previous episodes. The show also stars NeNe Leakes, Kandi Burruss, Phaedra Parks and Cynthia Bailey.
"If anyone is capable of blacking out and not taking responsibility for their actions, they should not be in this type of environment," she said. "They do not need a stage such as this."
Moore, an actress and former Miss USA, said the decision is up to the producers on whether Williams returns to the show. Bravo has not commented on the incident and has not addressed who will be back for the next season.
Williams' attorney, Joe Habachy, said in an emailed statement last week that the battery claim against his client is unfounded and that Williams looks forward to clearing her name. Habachy said Williams plans to contest the charge and file aggravated assault charges against Moore.
A rep for Williams did not return a request for comment on Monday.
Moore said she still hasn't spoken with Williams since the incident.
"She is a granddaughter of a civil rights leader," Moore said of Williams, whose grandfather was the late Hosea Williams. "She does not have the tools to navigate this process. It's just very unfortunate and sad. If I was in her position, the first thing I would do is apologize."
