For what possible reasons would a corrections officer help prisoners escape, other than sex, money or using the prisoners as a fence for drugs?

In upstate NY, two prisoners escaped almost three weeks ago. One was just shot dead by NYS police. They were in a maximum security prison. It was found out that one of the female employees was in some kind of relationship with them and helped them. She was arrested. It was also discovered that one of the corrections officers was assisting, too. He was arrested the other day.

That corrections officer started working with the state prison system in 1987. Almost 30 years he had this career. Now he helps convicts escape by giving them tools and allowing them to re-wire the circuit box outside their cell.

I know we are speculating. What could possibly be some reasons why someone would risk their freedom and their pension to help prisoners escape, other than money (them paying him), sex (sexual relationship), or him using the prisoners as a fence for drugs (him supplies them with drugs and they sell the drugs inside the prison)?
