RE: Are Humans Good By Nature? Or is This Something That Has to be Taught?
Humans first and foremost want to survive and they have done a good job at that in the last few thousand years. The key for our survival is adaptation. Our brains and hands allowed us to adapt to all climates and environments and to protect ourselves against competing animals.
Now when we feel that our survival might be threatened, we want to defend ourselves. This is where "bad" actions come from basically.
That's why we need to build a society where everybody is treated fairly, feels accepted, worthy and safe. Of course that's impossible. A little neglect at home and a bully at school are enough to turn a human being into a "bad" person...
The people who did the most horrible things in history usually suffered injustices, humiliation and failure themselves. Later in life they want to make it "right"
