Execute the gutted man
From Lord Of Utterdom
You grasp the fellow by his hair, yanking his head back. He begs you to let him live, but you won't spare this ruffian. You put your blade to this throat and draw it quickly across, splitting him open like a broiled pig. He sputters, gushing blood from his wound, and collapses into the dirt.
You wipe your sword across the back of his shirt, cleaning it of gore, then slide it into your hilt. You decide it would be rather foolish to ride through the darkness in search of the third man, so you simply let him go, sure he's far enough now to be no real threat.
The camp site is a mess, so there's no point trying to sleep. Also, the blood and corpses might draw wild animals. The stars are bright enough to guide you, and you're now brimming with adrenaline, so you might as well get on with your ride.
