As a soldier I will not judge those men in that video.......god will do that for me......but as a soldier; my job is to not allow my men to do the same, or allow orders to be given to my soldiers that place them in the same position as them.
These men have their demons now and they must live with them, telling soldiers that if they stab a man/enemy to death they will be rewarded.......that commander has already condemned his men to a life of hell.
I'll leave you with a quote, this quote is not for those men sitting at that table, this quote is aimed straight at their commanders who allowed this to happen
The darkest souls are not those which choose to exist within the hell of the abyss, but those which choose to break free from the abyss and move silently among us.....
