from There Is a ‘Worst Sin’: Evil in God’s Name by Dennis Prager in The National Review
When an irreligious person commits evil, it doesn’t bring God and religion into disrepute. But when a religious person commits evil in God’s name he destroys the greatest hope for goodness on earth — belief in a God who demands goodness, and who morally judges people.
The Nazis and Communists were horrifically cruel mass murderers. But their evils only sullied their own names, not the name of God. But when religious people commit evil, especially in God’s name, they are not only committing evil, they are doing terrible damage to the name of God.
In our time, there are, unfortunately, many examples of this. The evils committed by Islamists who torture, bomb, cut throats, and mass murder — all in the name of their God — do terrible damage to the name of God.
