I think this explains something of our human nature that we would not even know we have: It is coded within us to help people in need as we can very well be there at any future moment.

Just think about it, we are a social species and without this type of behaviors it makes no sense for individuals to stay together. It is a strategy of our genes to keep successfully replicating.

But even so, I agree with the author there is something really spiritual about this: deeply contradictory but firmly rooted in our nature.
