People may decide that's unfortunate but ultimately still the right decision; as you note, it's not the only piece of information. But right now many people are not making that decision actively. I haven't surveyed people formally, but in my discussions around the subject very few people guess the death tolls are anywhere near the real numbers. Many people have the impression that, yes, the U.S. strikes are imperfect, but generally accurate and with only a handful of innocent people occasionally being killed.
Starvation, Poor infrastructure, poor medication, poor parenting, etc.
Lots of it is preventable. Should we keep tallies just so we know how (young) people are dying?
You know why people don't make a big deal about those greater tallies? Because it's not a political message which aligns with someone's particular politics. Not because they would be harder to influence.
EDIT: Or any other crime against humanity. Nazis did holocaust for the "great good". This same reason was used for many communist crimes as well.
