There is a long way between not valuing another's child over your own (reasonable), and deliberately snipering 3-year-olds between the eyes (pure evil).

I wouldn't support that in most contexts. But cases like this (if even substantiated) are often used as emotional arguments against an otherwise justified conflict.

I can support it in no context. Zero.
Of course it will be used as an argument, and of course it will trigger an emotional response. It is that evil.
What would you do if your child was shot like that? Shut up and not mention it so people don't accuse you of emotional manipulation!?
