@mahtan Kids can be pretty amoral, before developing them, but it's hella disingenuous to say they're worse for violence. Worse for lack of compassion possibly, but kids don't do things on the same scale.
Also nah, wars aren't really for anyone's interest, besides power and profit's interest I guess. The best case scenario of a war is it being a response to someone else doing something really bad, which is in it's own right internally 'war like', but most of the time it's just one side pretending the other side did something of that level of justification.
Also that line did seem a bit silly after showing those kids like that, but obviously he means on a grander scale, which isn't bad. This world is infinitely more ravaged by war than the real world, some kids can still smile and laugh but I'm sure there's plenty that aren't.
