The Boston Marathon bombings showcased the good and the bad of humanity. The bad comes from the two Muslim brothers from Chechnya who killed three people and gruesomely injured over 100 more with two pressure cooker bombs. The good is from the bystanders, some who just completed a marathon (!), who quickly took action among the chaos, unsure if more bombs would explode, to help victims to safety. Some people literally ripped the shirt off their backs to make tourniquets for victims rapidly losing blood.
