That is a tough one to answer. I have seen good people do bad things and vice versa. But I also think that both are survival mechanisms. I do agree that it is a generalized idea because society so often wants one or the other to explain away things. I don't know how many times that I have heard things like: he was a good neighbor and I can't understand why he would have murdered his wife or she was such a bad kid growing up, now look at well she turned out. Great question, definitely has me thinking about it.

Good and bad are subjective and extremely limited.

I prefer life affirmative and life negating or various other ways to describe opposing forces in nature and the natures of our kind.

It also discloses evil in the form of life thwarting actions committed and perpetuated by religions against those trapped in them from the earliest stages of life.

Positive / Negative It's what balances the planet. Good/bad is subjective

Possibly a question of intent rather than action.

I think the human race defines them pretty well.

Are you speaking of objective absolutes? In that case, no.

It does lack factual validity. That said, I do believe there is a 'good' in the broader sense of things that are good for or to the majority of people. It may not be 'good' in some cosmic sense, or as taken apart from the interests of those involved, but it still exists subjectively. The same for 'bad'.

No

Okay.
