Ha! The Roman Legions were the friends of all, and spread tranquility throughout the ancient world after crucifying Christ. The Persian Empire consolidated its hold on the Middle East without so much as a single scuffle. In China, the Qin empire was such a blessing to all they immediately replaced it with the Han Dynasty which never harmed a flea. Genghis Kahn spread peace and light throughout Asia and Europe.
There sure wasn’t any evil in the Dark ages, or in the Crusades, or the Inquisition, or the great plagues. The Spanish Conquistadors were so incredibly tolerant of the native American culture, and the American settlers went out of their way to be a great blessing to the indigenous peoples they encountered. And the slave trade was not at all evil, it was meant only to rescue poor African tribesmen and give them all the benefits of civilization. The Civil War was so named because it was characterized by civility and brotherly love. WWI didn’t involve any poison gas, and WWII was a love-fest in which 60 million people were granted the chance to go to heaven early. Hitler was a great hero of tolerance and the war didn’t end when Hiroshima and Nagasaki got vaporized. Evil only broke out yesterday.
Now, setting aside that alternate universe and returning to the one based on reality, the Bible doesn’t give us a clue about when the end will come. In fact, it tells us that No man knows that time, not even the Angels in Heaven. But that hasn’t stopped doomsday prophets from declaring themselves better than the angels. And after 2,000 years of being eternally wrong, one of these days, or years, or centuries, or millennia they will probably be right.
