Hélder Câmara said this quote
“ If there is some corner of the world which has remained peaceful, but with a peace based on injustices the peace of a swamp with rotten matter fermenting in its depths - we may be sure that that peace is false. Violence attracts violence. Let us repeat fearlessly and ceaselessly: injustices bring revolt, either from the oppressed or from the young, determined to fight for a more just and more human world. ”
