Then I accept responsibility for being "part of the problem". I assume you have excellent inside information that they are proven terrorists, were given a trial, and legally executed. My hat's off to you for your in depth analysis.
OTOH, if you accept any prisoner killing by guards, then I suggest you are part of a much larger problem, far more damaging to our credibility and our place as a moral leader in the world. If you can accept as moral, those pictures all over the news, the video of a chopper using civilians for target practice, and now possible prisoner torture and homicide, then the word "moral" means something very different to each of us.
I'm not judging any soldier until I see the evidence, but anyone guilty of torturing or murdering a prisoner deserves the most severe punishment legally available. Those examples do not represent the military I know and love.
