Cruelty - the worst thing we can do?

As Richard Rorty tells it (and he gets this from Judith Shklar), a liberal is someone who thinks that 'cruelty is the worst thing we do'.

Shklar herself wrote:

Sins are transgressions of a divine rule and offenses against God; pride, as the rejection of God, must always be the worst one, which gives rise to all the others. Cruelty, as the willful inflicting of physical pain on a weaker being in order to cause anguish and fear, however, is a wrong done entirely to another creature. When it is marked as a supreme evil, it is judged so in and of itself, and not because it signifies a rejection of God or any other higher norm. It is a judgement made from within a world where cruelty occurs as part both of our normal private life and our daily public practice. By putting it irrevocably first—with nothing above it, and with nothing to excuse or forgive acts of cruelty—one closes off any appeal to any order other than that of actuality.

Cruelty stands alone as a kind of self-referencing evil: for Shklar it is evil on its own terms and not because of some higher norm. Christians may loath cruelty, but unless they put it first and worst, she argues, they will always find a reason somewhere to excuse it. She sites Christian history to prove it - the terrible episode of the Conquistadors being just one.

Of course, liberal democracies have also been complicit in cruelty - whether by participating in economic systems which produce it or by the explicit use of torture in war.
