1. Because those people annoy me. 2. Not all humans, only the "mainstream", the conformist crowds, I mean. 3. Isn't this the thread we talk about why it's retarded in games?
It's not really a belief of a fictional society, not even close. As I've said before, that society had already killed millions of children and largely doesn't care much of children as clearly seen in the game. It just the developer's "sacred children" view reflected in the game. They clearly never thought that it would annoy some people. Just like newly parents who think everyone would love their brats as much as they do. Actually, the more you think about that, the more you realize that Fallout could very well be made by Bethesda. Same shit really.
I'm guessing you're the shitposter of NMA?
That isn't a sound argument. Hitler had a terrible childhood, but he didn't grow up in a post-nuclear-apocalyptic society similar to Fallout's setting. Also, that's just one child in the world, out of millions upon millions of other children in the world. It should be obvious that if a nuclear war were to happen, similar to what happened during the Great War, the world population would have a stark decline, which means the minor population would also suffer from this. Yes, a previous generation of children (who grew up as adults, by the way) caused the destruction of human civilization, but we use history to reflect on atrocities like this, and try to do every we can so we repeat them. The future generations are different, because they're already reestablishing civilization. We see this in New Vegas, Fallout 2, and even in Fallout 1 in certain cases.
There is a difference between killing a child and an adult, seeing how killing the former clearly promotes a larger reaction. Also, children are inherently more vulnerable than adults, so it's less likely you'll get much resistance from that child.
