Humans are NOT naturally ‘nasty’.
Nietzsche was “scientifically invalid” all along?
That is, if you trust this guy:

That’s Frans de Waal, a biologist at Emory University in Atlanta. He says humans have lots of pro-social tendencies for reciprocity, fairness, empathy and consolation.
“Until just 12 years ago, the common view among scientists was that humans were nasty at the core but had developed a veneer of morality – albeit a thin one. But human children – and most higher animals – are moral in a scientific sense, because they need to cooperate with each other to reproduce and pass on their genes” - de Waal.
So there, humans are nice … deep inside.
Uhmm…

Don’t worry, Nietzsche. You have my vote on this.
