Question: Why doing the right thing is not always easy?
Answer: Because we don’t know what the “right thing” is!
We are all born with an inherently egocentric, subjective consciousness, perception. What we consider right/wrong is true only from our own self-serving, self-justifying viewpoint.
And since we exist in a fully integrated, interdependent system where each calculation, action should be aimed at the well-being of the whole collective, “our right” is almost certainly bad for the collective.
As they say, “the road to hell is paved with good intentions”, because those “good intentions” are inevitably good only for ourselves.
In order to do the “right thing” first we would need to acquire a completely selfless, objective viewpoint – through a special educational method in a “laboratory-like” environment.
