Omen III: The Final Conflict ending / spoiler

Kate kills Damien (Sam Neill) with one of the daggers after he uses her son as a shield when he is attacked by one of the priests. Before dying, Damien sees an angelic figure in the sky and says "You haven't won. You've gained nothing with this." The final scene is the head priest with Kate's son in his arms and passages from the Book of Revelation appear on screen.
