Graham Greene said this quote

The Church is in the world, it is part of the suffering in the world, and though Christ condemned the disciple who struck off the ear of the high priest's servant, our hearts go out in sympathy to all who are moved to violence by the suffering of others. The Church condemns violence, but it condemns indifference more harshly. Violence can be the expression of love, indifference never. One is an imperfection of charity, the other the perfection of egoism.
