The Sad History of Humankind

The chronology:

Somewhere between 2 million and 200K years ago, Homo sapiens was formed out of a not-yet complete understood combination of its ancestor species.

Its main differentiating factor: its huge brain, enabling humankind to assert its dominion over other animals, and solve problems related to our survival.

But those big brains turned out to be both a blessing and a curse, largely insofar as we deemed that we need leaders, but those aspiring to that level of power were often morally terrible people.  Ask yourself about the ethical character of Xi Jinping, Kim Jong Un, Erdogan, Oban, and Donald Trump–and let me know what you come up with.
