Any one individual can be good or not, and please don't think I'm trying to imply that you aren't. But -- well, I don't know, have you seen how little it takes for people in this country to go just a bit mad, even in a small way? I don't exactly mean to compare killing children to the 2011 August Riots, but they both seem to me to have the same origin. It wasn't really some criminal underclass rioting in 2011, there was a surprisingly large number of otherwise ordinary people who joined in. And this, really, is what I am driving at. There are a great many people who, while they would never dream of killing someone in cold blood, don't need too much of an excuse to go a bit mental and lawless in other ways.
It doesn't take me much effort to not kill people at random, either. But experiments and history have both shown that it doesn't take all that much effort for ordinary people to turn nasty, very nasty indeed.
At any rate, to pretend that the natural state of humanity is to be nice and kind to everybody -- or, perhaps, to say that such behaviour is unusual, or reserved only for savages -- is to pull the wool over your eyes. Even in living memory we have examples of it in this country, and in countries we used to rule over. The point then is that to regard such people as savages is to pretend that they are not human -- but they are, and so are we.
