School governors have sacked a philosophy teacher from his job after discovering his secret life - as a blood smeared death metal rock singer.By day shaven-headed Thomas Gurrath, 29, discussed ethics with his 14-year-old pupils at his high school in Stuttgart.But by night he calls himself The Bloodbeast and writhes around on stage covered in animal blood with topless backing singers and his band Debauchery.The band's biggest hits include 'Kill Maim Burn' and 'Torture Pit'."It was very worrying to listen to his music and then realize he was teaching our children," said one parent.Shocked officials ordered Gurrath to quit saying his performances were a form of mental instability that made him unsafe to be around children.They ordered him to choose between teaching and his music - saying he could no longer teach anywhere in Baden-Wuerttemberg state unless he gave up the band.But Gurrath said he was too addicted to death metal music to quit and agreed to give up his career as a teacher instead.
