Even while we kill and punish we must try to feel about the enemy as we feel about ourselves — to wish that he were not bad, to hope that he may, in this world or another, be cured: in fact, to wish his good. That is what is meant in the Bible by loving him: wishing his good, not feeling fond of him nor saying he is nice when he is not.
C. S. Lewis (1898-1963) English writer, literary scholar, lay theologian [Clive Staples Lewis]
