Social environment bad (somehow, not tied to human nature because social environments come into being by themselves and exist even without humans, if I'm understanding this as you mean it

I've said this three times: neither I nor Andrew said societies are not created by people.

if people were responsible, they would be bad people. but the video tells us there are no bad people);

They are indeed bad people. I don't know why you think i would disagree, or that the video suggests people can't be bad. Of course they can.

What??

But look people are good because they come together sometimes.

Stick to your point. You were first claiming it said people aren't inherently bad or good. That's right. Then you slipped it to people can't be bad or good. That's a totally different statement no one claimed. Now, somehow the claim has morphed to saying that people are inherently good.

What?

Maybe if you are trying to make a point don't just drop a youtube link and expect people to understand the same thing as you did or expect them suddenly be enlightened. Did you understand it? Care to elaborate on what you understood from it? I did. Let's compare notes.

I can't decide if you're trolling or genuinely incompetent. It's not hard to understand.

Human nature is not a fixed concept. It's a buzzword thrown around by people trying to sell their philosophy to you. People do what they can based on their material conditions. We are not inherently pulled toward being pro social or anti social.
