I know what conditioning can have of effect. But I assume our difference is in a total different aspect. I assume, that any human being is naturally empathic, willing to help others without asking for compensation. That gifting someone is nothing exceptional but rather the norm.

And all egoism is something human have to learn from the society. To be selfcentric is something we learn.

I base this claim on the reality, that rarely people attack eachother. Even more rare is a physical attack. Most people know, that respecting others property helps securing order in a society. Therefore most people do not steal. I don't see the reason in fear of punishment. But rather in our friendly nature and the understanding that we all profit from friendly behaviour, while everyone looses in a system where the most violent wins.

Over the decades humanity always tends to soften more. Every generation tends to be more friendly and less violent. It is natural selction. Survival of the friendliest.

You have different beleave there. And I think this is where we differe. The rest is only symptoms of this very basic idea, of what is natural human behaviour.
