Yet she must die, else she'll betray more men.Put out the light, and then put out the light:If I quench thee, thou flaming minister,I can again thy former light restore,Should I repent me: but once put out thy light,Thou cunning'st pattern of excelling nature,I know not where is that Promethean heatThat can thy light relume.
William Shakespeare, Othello
