This seems a bit made up. Again, the law makes no difference.
Regarding this moral scale, I disagree. I think the vast majority of the world sees it as binary. Murder bad. Self defense okay. Either/or, no sliding scale present. Do you have any sort of evidence?
which is why - as I pointed out earlier - in murder statistics and deaths in wars, children form a far smaller proportion of the deaths in comparison to the total of children, than people of other ages for in proportion to the total of people of those ages.
This is not sound. There are many reasons children could die in wars less, with evacuation from conflict zones being a big one. Similarly with crime, where things like gang violence will never target them due to them not being gang members.
In practice child murder is pretty well correlated with the highest levels of sociopathy and psychopathy, so a military which practices high levels of child murder has higher levels of psychopaths and sociopaths in their midst
This is not sound. You point out leadership in the very next line, and leadership absolutely makes a big difference. One correlation is not enough to draw such a conclusion when there are other factors.
I’m academically inclined, personally, so I pay great attention to details and do not think with my feelings. So these details are important to me.
