Denethor

Denethor is the last steward of Gondor in The Lord of the Rings. His sons are Boromir and Faramir. He resented being only a steward and wanted his son Boromir to become king, but that was a position reserved for Aragorn. Upon learning of Boromir's untimely death, he went crazy and tried to burn Faramir alive; thwarted in this by his page Peregrin, he leaped onto the fiery bier and ended his life in flames.
