In 1983 the pope visited him and talk to him and for gave him. While in jail he converted to Christianity and changed his way of life. After he was forgiven by the pope and released from jail he was sent back to jail in turkey where he served until 2010. When he was released he went to the pope's grave and laid two dozen white roses on it.
