Yes, and the simple fact of the matter is that while avoiding underage casualties in war may be impossible and that is worth saying, it is also worth saying that “revolutionary terror targeting children doesn’t serve the ends of any revolution” and accepting that, even during a revolution, there are things you don’t do because they are so wrong that they undermine your cause.

I mean, that's wrong though. You don't know what the situation will be and what the stakes will be. What if the horrible act is the only thing you can do to try and stop something worse?

This is the mischaracterization, it's neither of those things. Saying revolutionary terror targeting children doesn't serve the ends of any revolution is just objectively wrong. And saying that we think it's acceptable is also wrong. Sometimes you have to do things that are unacceptable and you shouldn't try to justify them. You can clarify context to let other people make their own judgement without justifying these acts. Likely, they will have the same conflicting feelings you would.
