Actually, your worries are in the wrong place. Only some sort of freak would pine over the death of a cold blooded mass murderer of women, children and our own troops, and condemn the soldier who did the world such a favor, during a BRUTAL war against that mass murderer and his ilk.
Ours is the most disciplined military on earth, and in all frankness friend, this sort of wartime event was once expected by reasonable people to happen with regularity. It DID in fact happen all the time and the military just looked the other way, quite pleased that a cold blooded murderer of women and children, and a killer of our own troops, has "expired". - Remember, this wasn't some young kid forced into random killing by Taliban elders and leaders. This was a vicious, fully matured Taliban LEADER. Of the sort who not only kills, maimes and tortures women and children and US troops, but forces others to do the same. He sat down and carefully planned his murders and terrorism, with jihaadist GLEE. Is it really a human being that does such things, or a soul that has given itself completely over to the Devil? The Devil has him now, and our troops and the world have greatly benefitted.
Fine. Try Mr Taliban first. A PFC should not be setting policy, especially a nutter.
