Men without morals are more dangerous than any type of ghoul, monster or demon. Darrin knew this all too well. The back alleys of Chernarus held such evil in them that the only hope of survival was joining them.
Left as a wailing baby outside of a fire hall, Darrin grew up without hope of a regular life. He was still a child when the civil war broke out. He was a desperate young child, who needed someplace to call his own. He joined the rebels, sitting in shadows and on top of roof tops. Armed with a pair of binoculars and a radio, he alerted his fellow troops to CDF soldiers. The rebels took care of him, treated him like a son. Feeding him and bringing him toys.
When the war ended he fled Elektrozavodsk , as his fellow revolutionaries were apprehended or killed. Being a teenager now, he knew what the rules were to survival. Evasion. Evading responsibilities, evading CDF soldiers, evading the law.
When the disease came, he was lurking around Pavlovo, and he saw a group of soldiers, United Nations, being slaughtered. He waited a few days, and eventually returned to find most of the infected were gone. He took what he could and ran.
