I was capable of evil

Something had gone wrong. I'd come to this war a quiet, thoughtful sort of person, a college grad, Phi Beta Kappa and summa cum laude, all the credentials, but after seven months in the bush I realized that those high, civilized trappings had somehow been crushed under the weight of the simple daily realities. I'd turned mean inside. Even a little cruel at times. For all my education, all my fine liberal values, I now felt a deep coldness inside me, something dark and beyond reason. It's a hard thing to admit, even to myself, but I was capable of evil. I wanted to hurt Bobby Jorgenson the way he'd hurt me. For weeks it had been a vow--I'll get him, I'll get him--it was down inside me like a rock. Granted, I didn't hate him anymore, and I'd lost some of the outrage and passion, but the need for revenge kept eating at me. At night I sometimes drank too much. I'd remember getting shot and yelling out for a medic and then waiting and waiting and waiting, passing out once, then waking up and screaming some more, and how the screaming seemed to make new pain, the awful stink of myself, the sweat and fear, Bobby Jorgenson's clumsy fingers when he finally got around to working on me. I kept going over it all, every detail. I remembered the soft, fluid heat of my own blood. Shock, I thought, and I tried to tell him that, but my tongue wouldn't make the connection. I wanted to yell, "You jerk, it's shock--I'm dying!" but all I could do was whinny and squeal. I remembered that, and the hospital, and the nurses. I even remembered the rage. But I couldn't feel it anymore. In the end, all I felt was that coldness down inside my chest. Number one: the guy had almost killed me. Number two: there had to be consequences.
