As I explained in the video, and everybody seems to get it beside you, even though some things might still be blurry and undecided, there are things that we know are objectively better than others.
The word BETTER is subjective by definition as it is a human judgement.
That is why we have law and the stuff.
Because what one person finds 'better' is seen by another as 'worse', so completely the opposite.
And then most peoples opinions will fall in between these two extremes.
