" Christianity does not want us to reduce by one atom the hatred we feel for cruelty and treachery. We ought to hate them. Not one word of what we have said about them needs to be unsaid. But it does want us to hate them in the same way in which we hate things in ourselves: being sorry that the man should have done such things, and hoping, if it is anyway possible, that somehow, sometime, somewhere he can be cured and made human again. "
― C.S. Lewis , Mere Christianity
