As an English teacher, one of my favourite poems to teach, to pupils of almost all ages, is Chinua Achebe’s ‘Vultures’. In the poem, the speaker describes various images that uncomfortably combine love and violence: a vulture picking apart a corpse before nestling up to its mate; a Commandant at Belsen buying chocolate for his children whilst the ‘fumes of human roast… cling rebelliously to his nostrils’.
