ChillDoubt - //Sgt Blackman won't lose any more sleep over him and nor should he. //
As I understand it, Sgt Blackman is a marine, not a killing machine, and as a human being, I am sure he will think about that man and the situation in which he died, from now until he himself passes away - and as a husband and father, and therefore because he is a thinking sentient feeling individual, I would suggest he would not wish not to do so.
