Nature is selfish

Something I’ve been thinking about, according to Taoist teachers we should follow the way of nature. There is this assumption that nature is inherently good it’s just that goodness gets clouded with mind stuff. And so following its way will lead to the betterment of society, families, etc.

And yet from my own personal experience, I have 8 nephews and 8 nieces and all of them have been or are selfish as children. They don’t know how to share toys or blankets or food or anything really. They seem to be this way before they take on any ideology or belief system or have a conceptual framework informing their experience which almost all human adults seem to have. In other words they seem to be this way by nature. Humans have to be taught how to share it’s not something that comes to them naturally which seems to go against the Taoist way.

What do y’all think of this?
