I, too, love watching Olympic competition. It is a glowing example of the good that humans can accomplish. Few things tug at my heartstrings like watching an Olympian stand on teh podium and shed a tear as their national anthem plays. Even better if it's the American flag in the top spot.
As for the evil part, I take solace knowing that good men and women around the world are willing and able to put on a uniform, or pick up a gun, or even just take a stand to combat that evil. It's just too bad that these men and women rarely get the recognition they deserve, and the evil stands so proudly in the spotlight.
