There was never a question about the comparative effect on the victims. The issue is that execution and murder are different. Replacing one term with the other as if they are interchangeable is dishonest. Specifically, this tactic is posed to evoke an emotional reaction and implies the victim was targeted specifically.
I don't actually need to explain this to you, as you already know it, but (often paired with ncmncm) disregard it in some perverse trolling exercise.
If you walk up to my initial comment (which everyone seems to have forgotten about) - it had nothing to do with whether one was "better" than the other.
But rather, and exactly as stated in that comment: it was about the blatantly dishonest attempt, in the parent comment, to portray the situation as something that it obviously wasn't.
