Chase, thanks for posting this detail, but none of this sounds much different than some of the mountain fighting in the Cumberland region during the WBTS, when you seemed to have a replay of this very form of barbarity. Have you ever heard of something called the Sheldon Loral Massacre? Not sure where or when it took place, but it was quite an example of this type of excess.
I mean it's hard to imagine how hard a man's heart can become to laugh at a child begging for his life. Or to urinate on a vanquished foe who at one point had displayed such chivalry to his own enemy.
