Human nature has evolved considerably since we’ve climbed down the proverbial tree/been made in His own image.
Some of our ancestors used to eat their fellow human beings/the first brother had killed his sibling for profit while a sizeable proportion of the present humankind governs itself in a democratic manner.
No individual has ever been able to change, by themself, the human nature. Time and time again, this has been attempted in vain. Plato, Napoleon, Marx, Lenin, Hitler, Stalin…
Yet each of us can change their own persona. This is what Buddha and Jesus have been successfully teaching us.
This is how we’ve figured out that eating our brother might satiate our hunger for the time being but will never solve the problem. Feeding ourselves for the long run demands cooperation. It cannot be achieved through mindless/cut-throat competition.
As long as more and more of us understand this, we’ll have a fighting chance to survive. As a species.
