Rebel commander Abu Sakkar gained instant notoriety after footage emerged of him appearing to remove the organs of a pro-regime fighter and then eating them.
In a short video uploaded to YouTube, he says that he found the fighter had mobile phone footage showing the killing of children, rapes, dismemberment and torture.
"Every free Syrian who sees this; you don't know what they can do," he said.
He also warned that if the bloodshed in Syria continues "all Syrian people will be like me."
