You don’t need to be religious or not to realise that humans are intrinsically capable of good and that sometimes that capacity can astonish you.
And this kid probably thinks what he does isn’t “special”.
That’s the brilliant thing about being human. You can do the most extraordinary things and still think it’s perfectly normal.
