That's why Jesus talked a great deal about punishment, and the moral obligation to oppose evil with a strong and swift hand. Human evil must be confronted, he said, not merely contained. Depending on the threat, a kind of "pre-emptive strike" or judgment against evil might even be required: "Be afraid of the one who can destroy both soul and body in hell" (Matthew 10:28). Allow the darkness to roam unchecked, Jesus said, and it will devour individuals and entire regimes. That helps explain why in the New Testament we see the Son of God rebuking hateful mobs, casting demons into the abyss, chasing religious charlatans out of a temple with a whip. "Do not suppose that I have come to bring peace to the earth," he said. "I did not come to bring peace, but a sword" (Matthew 10:34).
