Highlander: The Series (1992) : 3x13

When a religious leader, John Kirin, dies on Anne's operating table and then returns from the dead, his believers know a miracle has occurred. MacLeod knows better. He watched as Kirin, then known as Kage, massacred POWs in the Spanish Civil War and left a band of Cambodian refugee children to die at the hands of the Khmer Rouge. Kirin swears that experience changed him forever, turning him from a man of war to a man of peace. When a tabloid reporter trying to get the goods on Kirin winds up dead in MacLeod's dojo, MacLeod is certain Kirin is responsible. Kirin protests his innocence and realizes the real killer is Matthew, one of his faithful disciples trying to protect him. Kirin confronts a disillusioned Matthew, who manages to kill Kirin before dying himself in a rain of police bullets. In the Tag, Kirin and MacLeod have made peace as Kirin takes to the road, hoping to do good elsewhere.
