"I guess the religious belief was the snowflake that pushed me over the edge."
Cain is 73-years-old and the longest serving warden in Angola history. He has gained world-wide recognition for his efforts in reforming the prison. Cain says his biggest accomplishment at Angola does not lie with the buildings on the prison campus.
"But what's in the hearts of the men here because that never really goes away. And that's the greatest change, the moral rehabilitation that we have. That's what counts."
Corrections Secretary Jimmy LeBlanc will appoint Cain's successor. Cain believes LeBlanc will select Dixon Correctional Institute warden Darrell Vannoy to replace him at Angola.
"He's very experienced and knows all the inmates and we won't miss a lick. I'm going to work with him through a transition period til we get everything really smoothed out and ensure we have public safety and the prison under control and it's stable."
